What does the code for a basic Python animation look like?
You can make a simple animation in Python with different libraries. Many people like using the matplotlib library. Matplotlib, a strong Python library, can make plots and do basic animations.
Here's an example of a basic Python animation using matplotlib:
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.animation import FuncAnimation
# Function to update the plot in each animation frame
def update(frame):
# Clear the previous plot
plt.cla()
# Generate some data points for the animation
x = np.linspace(0, 2*np.pi, 100)
y = np.sin(x + 2*np.pi*frame/100)
# Plot the data
plt.plot(x, y)
plt.xlabel('X')
plt.ylabel('Y')
plt.title('Basic Python Animation')
plt.grid(True)
# Create a blank figure
fig, ax = plt.subplots()
# Create the animation with the update function, 100 frames, and 100ms delay between frames
animation = FuncAnimation(fig, update, frames=100, interval=100)
# If you want to save the animation as a video file, you can use the following line:
# animation.save('basic_animation.mp4', writer='ffmpeg', fps=30)
# Display the animation
plt.show()
This code creates a simple animation that displays a sine wave. The update function makes new data points and updates the plot in each animation frame. The FuncAnimation class controls the animation. It calls the update function many times with different frame values.
In this example, the animation has 100 frames with a delay of 100 milliseconds between frames.
To save the animation as a video file:
- Remove the comment from the animation.
- Save line.
- Make sure you have ffmpeg installed.
- Before running the code, ensure you have installed matplotlib in your Python setup. You can install it using pip install matplotlib.
Using an animation library, how can you make line charts with various colors in Python?
You can use different libraries in Python to make line charts with colors and animations. I will teach you how to use Matplotlib's FuncAnimation to animate graphs.
Here's a step-by-step guide:
#Install the required libraries (if you haven't already)
pip install matplotlib
# Import the necessary modules
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.animation import FuncAnimation
# Generate your data: Create multiple datasets with different colors. For this example, let's consider two datasets, data1 and data2
x = np.linspace(0, 10, 100)
data1 = np.sin(x)
data2 = np.cos(x)
# Create a figure and an axis to plot the data
fig, ax = plt.subplots()
# Define the line objects for each dataset and set their properties
line1, = ax.plot([], [], color='red', label='Data 1')
line2, = ax.plot([], [], color='blue', label='Data 2')
# Define the initialization function for the animation
def init():
line1.set_data([], [])
line2.set_data([], [])
return line1, line2
# Define the update function for the animation
def update(frame):
line1.set_data(x[:frame], data1[:frame])
line2.set_data(x[:frame], data2[:frame])
return line1, line2
# Create the animation using FuncAnimation
frames = len(x)
animation = FuncAnimation(fig, update, frames=frames, init_func=init, blit=True)
# Display the animation or save it to a file (optional)
plt.legend()
plt.xlabel('X-axis')
plt.ylabel('Y-axis')
plt.title('Animated Line Chart with Different Colors')
plt.show()
This code makes a line chart that shows two datasets using different colors. You can customize the colors, data, and other properties per your requirements. To add more datasets, make new line objects and update their data in the update function.

Converting RGB to YCbCr can provide better results for image and video compression, color space conversions, and HDR processing. There are several reasons why we might need to convert RGB to YCbCr
Compression efficiency: YCbCr provides better compression results compared to RGB, especially in preserving image quality after compression. This is because the human visual system is more sensitive to changes in brightness (luma, Y) than to changes in color (chroma, Cb and Cr). Color space conversion: Some image processing tasks, such as color correction and color space conversion, may require transforming the image from one color space to another. For example, many image sensors capture the image in the YCbCr color space, and it may be necessary to convert it to RGB for display purposes.
OpenCV (Open Source Computer Vision Library) is an open-source and machine-learning software library. OpenCV is a computer vision library written in C++ and widely used for image and video processing. OpenCV provides a vast array of image and video processing functions that can be used in various domains such as:
- Object detection and recognition
- Image and video segmentation
- Face and feature detection
- Object tracking
- Image restoration and enhancement
- Stereoscopic vision
- Motion analysis and object tracking
- 3D reconstruction
RGB and YCbCr are color spaces used in digital image processing.
RGB stands for Blue, Green, Red, and is an encoding of the RGB (Red, Green, Blue) color space. BGR is used in computer vision and image processing applications and is the default color format for the OpenCV library in Python.
YCbCr, on the other hand, stands for Luma (Y) and Chrominance (Cb, Cr), and is a color space used in digital video processing. YCbCr separates the brightness information (luma) from the color information (chroma), which allows for more efficient compression. YCbCr is used in many image and video compression standards, such as JPEG and MPEG. In summary, BGR is used in computer vision and image processing, while YCbCr is used in video processing and compression.
In this solution, we are going to learn how to convert the RGB image to YcbCr using opencv.

In Python, the "where" condition is used in conjunction with Boolean indexing to filter the elements of an array, list, or DataFrame based on a specific condition. The condition is specified as a Boolean expression, and the elements that satisfy the condition are kept while the elements that do not are removed.
You can fetch the value of a particular column with a WHERE condition using a “SQL SELECT” statement.
- SQL SELECT: Using the SQL SELECT command, you may query a database and get specified data from one or more of its tables.
In the WHERE clause, you may also include several criteria by using logical operators like "AND," "OR," etc.
- AND: In a WHERE clause, several criteria can be combined using the SQL AND statement. When all criteria are true, rows from a table are returned using the AND statement.
- OR: In a WHERE clause, multiple conditions can be combined using the SQL OR statement. When at least one of the requirements is true, the OR statement is used to get rows from a table.
For better knowledge of fetching the value of a particular column with where condition, you may have a look at the code below.

We will locate a specific group of words in a text using the SpaCy library, then replace those words with an empty string to remove them from the text.
Using SpaCy, it is possible to exclude words within a specific span from a text in the following ways:
- Text pre-processing: Removing specific words or phrases from text can be a useful step in pre-processing text data for NLP tasks such as text classification, sentiment analysis, and language translation.
- Document summarization: Maintaining only the most crucial information, specific words or phrases will serve to construct a summary of a lengthy text.
- Data cleaning: Anonymization and data cleaning can both benefit from removing sensitive or useless text information, such as names and addresses.
- Text generation: Adding context or meaning to the generated content might help create new text by deleting specific words or phrases.
- Text augmentation: Text can be used for text augmentation techniques in NLP by removing specific words or phrases and replacing them with new text variations.
Here is how you can remove words in span using SpaCy:

QUESTION
Getting the error "Nested CSS was detected, but CSS nesting has not been configured correctly" in React app?
Asked 2022-Mar-23 at 09:04I've been upgrading my CRA project to TailwindCSS 3, but now CSS nesting no longer works. Upon starting the server, the console spits out:
1(8:3) Nested CSS was detected, but CSS nesting has not been configured correctly.
2Please enable a CSS nesting plugin *before* Tailwind in your configuration.
3See how here: https://tailwindcss.com/docs/using-with-preprocessors#nesting
4However, I don't see what must be done to correct this. I've tried setting up a plain CRA project with Tailwind (following this guide) just to make sure I have no conflicts, and still no success.
postcss.config.js:
1(8:3) Nested CSS was detected, but CSS nesting has not been configured correctly.
2Please enable a CSS nesting plugin *before* Tailwind in your configuration.
3See how here: https://tailwindcss.com/docs/using-with-preprocessors#nesting
4module.exports = {
5 plugins: {
6 "tailwindcss/nesting": {},
7 tailwindcss: {},
8 autoprefixer: {},
9 },
10};
11As you can see, I have added the nesting plugin before Tailwind. It appears to me as if the plugin isn't being detected whatsoever. I've also tried replacing it with postcss-nesting with same outcome.
Note: I've also tried using the array syntax with require('tailwind/nesting') like the guide suggests.
Interestingly, removing all plugins from postcss.config.js (or using a require that fails to resolve) still outputs the same error, implying that this file isn't needed to get Tailwind to load. Maybe I am missing something that causes the whole postcss.config.js file to not be loaded in the first place?

54ANSWER
Answered 2022-Feb-03 at 18:38This is mostly just bad news.
Create React App's Tailwind support means that they will detect tailwind.config.js in the project and add tailwindcss to their existing postcss configuration. Source in CRA
The guide that Tailwind offers on their site creates a dummy postcss.config.js - Making changes in this file does not change the actual postcss configuration. (misleading if anything)
This is a known issue currently - Github discussion on Tailwind support PR between Adam Wathan (Tailwind founder) and Ian Sutherland (CRA maintainer). But it does not seem like there is an intention to be fixed soon.
If you want to use nesting (or any PostCSS plugin really) is to eject from CRA using:
1(8:3) Nested CSS was detected, but CSS nesting has not been configured correctly.

55After ejecting you can find CRA's postcss configuration in config/webpack.config.js - look for postcss-loader. Editing the configuration there can enable any postcss features.
PS: Look out for postcss-preset-env in the default configuration while enabling nesting. Tailwind requires you to edit configuration if this is present.

I created a blank Nuxt3 project by
1npx degit "nuxt/starter#v3" my-nuxt3-project

ANSWER
Answered 2022-Feb-22 at 10:55Actually moving the css imports into resources/js/app.js solves this problem. However, this results in the imported css to be included in the public/js/app.js, not the public/css/app.css.
QUESTION
How to get 2D scene coordinates of a 3D object in JavaFX
Asked 2022-Feb-02 at 12:28I'm trying the create a 3D subscene with objects being labelled using Label objects in a 2D overlay. I've seen similar questions to mine on this subject, and they all point to using the Node.localToScene method on the node to be labelled in the 3D space. But this doesn't seem to work for my case. I've taken example code from the FXyz FloatingLabels example here:
The Label objects need to have their positions updated as the 3D scene in modified, which I've done but when I print out the coordinates returned by the Node.localToScene method, they're much too large to be within the application scene, and so the labels are never visible in the scene. I've written an example program that illustrates the issue, set up very similarly to the FXyz sample code but I've created an extra SubScene object to hold the 2D and 3D SubScene objects in order to plant them into a larger application window with slider controls. The 3D scene uses a perspective camera and shows a large sphere with coloured spheres along the x/y/z axes, and some extra little nubs on the surface for reference:

142This likely means that the library (@angular/platform-browser) which declares BrowserModule has not been processed correctly by ngcc, or is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.
143
14445 export declare class BrowserModule {
145I have tried the following approaches to fix this issue,
- Tried deleting node_modules, deleted packacge-lock, cleared npm cache, and then finally npm installed, This approach has worked on many previous stack-overflow problems however for me the problem still persists.
- I have tried installing different versions of angular-cli, tried to match their compatibility with different node versions and different npm versions, that however I wasn't able to do properly because of multiple broken dependencies.
Please suggest some solutions, thank you

142This likely means that the library (@angular/platform-browser) which declares BrowserModule has not been processed correctly by ngcc, or is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.

142This likely means that the library (@angular/platform-browser) which declares BrowserModule has not been processed correctly by ngcc, or is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.

149QUESTION
Why does my tailwind output file not include the utilities and components
Asked 2022-Jan-21 at 16:43I've installed tailwind using npm install tailwindcss
I then create my src/style.css file and include
1 `@tailwind base;`
2 `@tailwind components;`
3 `@tailwind utilities;`
4When I run my build-css command I get a generated output.css file, but the file is only 425 lines long. It looks likes it's missing the components and the utilities. When I link my HTML to the output.css I get the base tailwind css styles applied, but utilities have absolutely no effect. I have followed the docs to the best of my ability as well as several tutorials with the same result every time. No clue what I am I doing wrong, the tuts I have watched show this file to be thousands of lines of code while mine is always 425.
ANSWER
Answered 2021-Dec-25 at 20:47You need to add a config js file for the tailwind engine, inside the config file use content attribute to define where is your HTML or JS files, the new engine automatically looks inside these files and compiles only the classes that you used.

QUESTION
How can I compare system_clock::now() to a local time in c++20?
Asked 2022-Jan-20 at 14:01I am testing a library like follows:
1std::chrono::system_clock::time_point FromDateTime(const DateTime& dateTime)
2{
3 std::tm tm{};
4 tm.tm_year = dateTime.Year - 1900;
5 tm.tm_mon = dateTime.Month - 1;
6 tm.tm_mday = dateTime.Day;
7 tm.tm_hour = dateTime.Hour;
8 tm.tm_min = dateTime.Minute;
9 tm.tm_sec = dateTime.Second;
10
11 const auto& time = std::mktime(&tm);
12 const auto& timePoint = std::chrono::system_clock::from_time_t(time);
13
14 return timePoint;
15}
16
17TEST_F(MyLibraryFixture, GetDateTime)
18{
19 // Arrange
20 const auto& now = std::chrono::system_clock::now();
21
22 // Act
23 const auto& actual = _testee->GetDateTime();
24
25 // Assert
26 const auto& timeDiscrepanceInSec = std::chrono::duration_cast<std::chrono::seconds>(FromDateTime(actual) - now);
27 ASSERT_TRUE(timeDiscrepanceInSec.count() < 10);
28}
29The DateTime type is just a raw struct with the above used fields. The call
1std::chrono::system_clock::time_point FromDateTime(const DateTime& dateTime)
2{
3 std::tm tm{};
4 tm.tm_year = dateTime.Year - 1900;
5 tm.tm_mon = dateTime.Month - 1;
6 tm.tm_mday = dateTime.Day;
7 tm.tm_hour = dateTime.Hour;
8 tm.tm_min = dateTime.Minute;
9 tm.tm_sec = dateTime.Second;
10
11 const auto& time = std::mktime(&tm);
12 const auto& timePoint = std::chrono::system_clock::from_time_t(time);
13
14 return timePoint;
15}
16
17TEST_F(MyLibraryFixture, GetDateTime)
18{
19 // Arrange
20 const auto& now = std::chrono::system_clock::now();
21
22 // Act
23 const auto& actual = _testee->GetDateTime();
24
25 // Assert
26 const auto& timeDiscrepanceInSec = std::chrono::duration_cast<std::chrono::seconds>(FromDateTime(actual) - now);
27 ASSERT_TRUE(timeDiscrepanceInSec.count() < 10);
28}
29_testee->GetDateTime();
30gives a DateTime struct back and the date time is actually local time. For some reason inherent to the library I am testing, I need to compare the local time with the time it is now. My code above seems to be working fine, I "hope" it will still work when we get back to Summer time.
Now, c++20 exposes a lot of date time utilities. I have browsed the documentation, I have tried some stuff, but I was not able to come up with a reliable counterpart to the above snippet. Is it any possible (I mean, without using std::mktime and the strange std::tm)?
The closest I was able to come is this, but it is still wrong (I get a discrepancy of one hour):
1std::chrono::system_clock::time_point FromDateTime(const DateTime& dateTime)
2{
3 std::tm tm{};
4 tm.tm_year = dateTime.Year - 1900;
5 tm.tm_mon = dateTime.Month - 1;
6 tm.tm_mday = dateTime.Day;
7 tm.tm_hour = dateTime.Hour;
8 tm.tm_min = dateTime.Minute;
9 tm.tm_sec = dateTime.Second;
10
11 const auto& time = std::mktime(&tm);

57 zoned_time zt{current_zone(), local_tp};
58 return zt.get_sys_time();
59}
60You were on the right track with creating a local_time using local_days.
There's no need to explicitly name the year_month_day type. This is generated for you using the / notation.
Once you have the local time, you can associate it with your computer's local time zone by constructing a zoned_time with current_zone() and the local_time.
Then you can extract the sys_time out of the zoned_time. The sys_time is a time_point<system_clock, seconds> (seconds-precision system_clock::time_point), which is UTC (excluding leap seconds). And this implicitly converts to the return type: system_clock::time_point.
If desired, you could interpret the local_time with respect to some other time zone, rather than your computer's local time zone. For example:
1std::chrono::system_clock::time_point FromDateTime(const DateTime& dateTime)
2{
3 std::tm tm{};
4 tm.tm_year = dateTime.Year - 1900;
5 tm.tm_mon = dateTime.Month - 1;

9 tm.tm_sec = dateTime.Second;

QUESTION
Count trailing newlines with POSIX utilities or GNU coreutils or Perl
Asked 2022-Jan-19 at 22:10I'm looking for ways to count the number of trailing newlines from possibly binary data either:
- read from standard input
- or already in a shell variable (then of course the "binary" excludes at least 0x0) using POSIX or coreutils utilities or maybe Perl.
This should work without temporary files or FIFOs.
When the input is in a shell variable, I already have the following (possibly ugly but) working solution:
1original_string=$'abc\n\n\def\n\n\n'
2string_without_trailing_newlines="$( printf '%s' "${original_string}" )"
3printf '%s' $(( ${#original_string}-${#string_without_trailing_newlines} ))
4which gives 3 in the above example.
The idea above is simply to subtract the string lengths and use the "feature" of command substitution that it discards any trailing newlines.
Test-Cases:1original_string=$'abc\n\n\def\n\n\n'
2string_without_trailing_newlines="$( printf '%s' "${original_string}" )"
3printf '%s' $(( ${#original_string}-${#string_without_trailing_newlines} ))
4printf '' | function results in: 0
5printf '\n' | function results in: 1
6printf '\n\n' | function results in: 2
7printf '\n\n\n' | function results in: 3
8printf 'a' | function results in: 0
9printf 'a\n' | function results in: 1
10printf 'a\n\n' | function results in: 2
11printf '\na\n\n' | function results in: 2
12printf 'a\n\nb\n' | function results in: 1
13For the special cases when NUL is part of the string (which anyway just works when reading from stdin, not when giving the string in the shell via avariable), the results are undefined but should typically be either:
1original_string=$'abc\n\n\def\n\n\n'
2string_without_trailing_newlines="$( printf '%s' "${original_string}" )"
3printf '%s' $(( ${#original_string}-${#string_without_trailing_newlines} ))
4printf '' | function results in: 0
5printf '\n' | function results in: 1
6printf '\n\n' | function results in: 2
7printf '\n\n\n' | function results in: 3
8printf 'a' | function results in: 0
9printf 'a\n' | function results in: 1
10printf 'a\n\n' | function results in: 2
11printf '\na\n\n' | function results in: 2
12printf 'a\n\nb\n' | function results in: 1

Create new color scheme for dark-light mode in bootstrap sass
Asked 2022-Jan-16 at 19:50I want to create dark mode for a web site which use bootstrap. I have to add new root class which includes all boostrap colors. Here is my colors.scss:
1$primary:#065FC6;
2$secondary:#263C5C;
3$success:#49C96D;
4$danger:#FD7972;
5$warning:#FF965D;
6$light:#F8F8F8;
7$body-color: #263C5C;
8
9$custom-colors: (
10 "brd-default": $body-color
11 );
12
13I want create new class like this:
1$primary:#065FC6;
2$secondary:#263C5C;
3$success:#49C96D;
4$danger:#FD7972;
5$warning:#FF965D;
6$light:#F8F8F8;
7$body-color: #263C5C;
8
9$custom-colors: (
10 "brd-default": $body-color
11 );
12
13:root.dark{
14 // override colors and classes for dark mode
15 $primary:#012345;
16 $secondary:#111111;
17 $success:#222222;
18}
19So how can i copy and paste all bootstrap colors for new color scheme?
If i can add colors, i will change HTML class so my root(color scheme) will be:
in my styles.scss:
1$primary:#065FC6;
2$secondary:#263C5C;
3$success:#49C96D;
4$danger:#FD7972;
5$warning:#FF965D;

8
9$custom-colors: (
10 "brd-default": $body-color
11 );
12
13:root.dark{
14 // override colors and classes for dark mode
15 $primary:#012345;

23ANSWER
Answered 2021-Aug-07 at 20:32As explained here, there's no way to attach a class to :root. However, you don't need this to achieve what you want.
Simply make a dark class then you can add that as desired to the html or body tag.
Make all the needed theme color changes inside .dark{}, and then @import "bootstrap". When .dark doesn't exist on the body, the theme colors will return to Bootstrap defaults.
