QUESTION
I have been following a tutorial from Sentdex to create a button and make it functional. I tried to change it as per my requirement. When I click on the button, I want the function(another screen) to execute. I placed a button in the function(another screen) where I can go back to the main page. But when I click on the button, it goes to the other function only when I clicked the mouse and the output is displayed just until I click the mouse. It does not go to another screen and keeps on staying at initial screen.
...ANSWER
Answered 2021-Jun-06 at 10:42You have to add a variable that stores the current state of the game (game_state
). Change the variable when a button is clicked and draw different scenes depending on the state of the variable:
QUESTION
So I've done the hardest part of actually displaying the SVG with the help of Giovanni Gatto(credit: https://pythonprogramming.altervista.org/tkinter-shows-an-svg-file/)
I've modified the code to fit my needs, but after implementation, rather than it assigning the SVG to each button individually, it will only display it on the last button on the frame.
I can create a function for each button, but that would be inefficient, what is the best way to approach this?

Answered 2021-May-08 at 20:29I can't test it but problem can be bug in PhotoImage
which removes it when it is assigned to local variable.
Normally you could assign `PhotoImage to global variable or to other class
QUESTION
I'm trying to scrape the Tradingview web page with my own chart to read boolstates.
Here what I mean exactly
With this HTML code of the website
I'm working with Debian/Linux on a Server and programming with Python. I tried using BeautifulSoup to read the page and found out that BeautifulSoup can't run JavaScript and therefore can't display everything in HTML to work with it.
This code only outputs brackets []. So it didn't found the class I'm searching for
...ANSWER
Answered 2021-Mar-13 at 20:35Might be on the heavier side, but have you thought about doing it with Selenium? You'd be able to run the full browser. If I'm not mistaken, you can still use BeautifulSoup with it as well.
As for the route, you can probably find brokers that offer that info via a proper API, which would obviously be the ideal scenario. Interactive Brokers comes to mind.

QUESTION
I am trying to get the logic of using jQuery AJAX and Flask, however I am not coming right. I have been following tutorials here and here, but no resolution. To get the logic - I simply want to input dates in two separate fields, and return those dates to the same page in a normal
tag. My suspicion is a problem in the server receiving the dates. Submitting the relative form does not return anything to #result
HTML FORM
...ANSWER
Answered 2021-Feb-05 at 21:58Please use the button to send the form, an anchor within the form does not make sense.
I would advise you to use the "submit" event
of the form, although the "click" event of the button would also work. The preventDefault
function bypasses the standard behavior of the form, so that you can send the form yourself using getJSON
. To serialize the form data, I use the serialize
function which converts all form data into a conforming string. Thus the data is sent as "application/x-www-form-urlencoded".
The variable $SCRIPT_ROOT
is not used by me in this example because it is
basically empty under localhost and is not absolutely necessary.
QUESTION
I'm new to keras. This code is working on classifying between MRI images of brain with or without tumor. When I run model.evaluate()
to see the accuracy I get very high loss value even it is low when I'm training the model(normal less than 1) and I get the following error:
ANSWER
Answered 2021-Jan-18 at 06:23Ignore the warning.
Your low training loss and high evaluation loss means that your model is overfitted. Stop training when your validation accuracy starts to increase.
QUESTION
I am trying to dynamically update a matplotlib from a .txt file that periodically updates.
For this, I used the following tutorial.
https://pythonprogramming.net/python-matplotlib-live-updating-graphs/
The .txt file looks like such
...ANSWER
Answered 2021-Jan-14 at 12:47I created the code with the understanding that the intent of the question was to draw a graph based on the row-by-row data by retrieving the values from an updated, localized text file. The main points that I modified are the initial settings and updating the values in the animation function.

QUESTION
Im trying to make a very minor 2d game engine, and I am trying to get the user to select a file. I am using pygame to write my code, but to choose a file you would need tkinter or make your own file opener and I am to lazy to. I have two problems but i am only going to write my first one here. I have the name and location of the file and when i do img.imwrite("background.jpg")
it gives me an error, so I thought maybe I'll just run it in a seperate file to test if im writing it right, or it doesn't work, and i still get an error.
Code:
...ANSWER
Answered 2020-Nov-01 at 01:45imread
returns a numpy array of the image data. imwrite(filename,image)
(doc here) takes a name and image data, saving it in the specified format. You can't call imread
as if it were a method of the image data.
