lamb | monitoring tool for better visibility | Cloud Functions library

I'm facing a mathematical/programming problem which I don't really understand. In the following α,β,θc are given parameters, ϕ is the variable. I have to solve the equation Cp=0, where:

and:

The solutions that I have computed are:

Coding the above solutions with Python/Numpy, I find that:

• If β=0, then both solutions are correct: Cp(ϕ1)=Cp(ϕ2)=0.
• However, if β!=0 then Cp(ϕ1)!=0 (which is wrong) and Cp(ϕ2)=0. Why? I checked again and again the signs and terms on my coded expressions, they seem fine to me...

Here is the code:

What is the best way to do the same action across multiple lines of code in the RStudio source editor?

Example 1

Let's say that I copy a list from a text file and paste it into R (like the list below). Then, I want to add quotation marks around each word and add a comma to each line, so that I can make a vector.

Given a long string name = 'Mary had a little lamb'

and a pandas Series with pd.Series(data=['Mary', 'large', 'little lamb']) ,

is there a pandas string operation that could identify whether an entry is a substring of the longer string name ?

This is my first stack overflow question, so if I am presenting something wrong, please let me know. I am pretty new to computer programming, so I just have a small webpage where I am just implementing things that I am learning.

I made a little quiz with random trivia multiple choice questions you can take if you press a button. I am using window prompts to ask the questions and get the answers, and I have all of the questions and answers stored as objects with question/prompt and answer pairs. All of those objects are stored in an array in a variable called shortQuizPrompts. I already have the quiz working and everything, aka., It tells you after every question if you got the answer to that question right or wrong, and it gives you a grade afterwards... I also have it set up so that if you enter an answer that is not "a", "b", "c", or "d", it lets you know that it isnt a valid answer. Those sorts of things.

As of right now, you can choose how many questions long you want the quiz to be out of the 24 total questions I have so far. It just asks the questions in the order that they are stored in the array. For example, you will never be asked the last question in the array if you do not choose for the quiz to be the full 24 questions long. However, I want to make the quiz ask the questions in a random order, while also removing those questions from the array as to not ask the same question multiple times.

I have tried increasing the iterator while looping through the array to a random number from 0 to the length of however many questions they chose. Then checking to see if the iterator was larger than the length of the number of questions they chose, it would decrease the iterator until it found a question that is still in the array that it could ask...

If anyone knows how to go about doing that, it would be great. Sorry for the long question btw. I am pretty new to coding, so this is probably a simple answer, but I digress. I'm pretty sure I did everything right. Thx.

I am trying to add Simplebar scrollbar to the MUI Material Autocomplete component, instead of the default browser one. All works but doing that I've lost the ability to navigate the options list with the keyboard.

There is this snippet from the MUI docs

ListboxComponent If you provide a custom ListboxComponent prop, you need to make sure that the intended scroll container has the role attribute set to listbox. This ensures the correct behavior of the scroll, for example when using the keyboard to navigate.

But I have no idea how to do that.

The following code is from the MUI docs, first autocomplete example with custom ListboxComponenet and shortened movie list. (https://mui.com/components/autocomplete/)

I'm trying to make two List components: one of them is static and small, the second is incredibly large and dynamic. In the first List I store food categories: Alcoholic products, Soups, Cereals, etc. In the second List, the word is searched directly from the database - it can be anything: a dish or a category of dishes. Below is the code - it displays the start page. Initially, the first static and small List is located on it, as well as the Search component (Navigationview.seacrhable()). When you type a word into the search bar, the first List disappears and the second one appears. At the moment, both sheets are loaded asynchronously. This is necessary because the second sheet is really big (thousands of rows). This is where my problem begins. Sometimes, when you type a word into the search bar, a copy of this sheet appears on top of it, as shown in the image. It only happens for a fraction of a second, but it's still noticeable. The problem is most likely due to asynchronous loading, before I added it, the List was loading super slowly, but without such bugs.

My minimal reproducible example:

ContentView.sfiwt

Main List, displaying the food categories available for selection.

I am having a go at printing a sequence of strings, either using a newline between entries. Or printing them next to each other.

Would like to simplify this if I can.

When nwline=1, new lines are used between the printing of arguments. When nwline=0, arguments are printed on same line.

nl determines the number of arguments that get coloured using ctp.

I have some code which takes input from the user and stores it in a list. The list may have an odd or even number of elements, for example: my_list = ['Beef','Chicken','Eggs','Lamb','Nuts','Pork'] (even number of elements)

or my_list = ['Beef','Chicken','Eggs','Lamb','Nuts','Pork','Potatoes'] (odd number of elements)

I want to store my_list in a string variable, such so that when I print(var) or create a tkinter messagebox, my program will output two columns like this:

trying to dockerize this flask app... running the following

docker build --tag flask-website .

works, output successfully built, successfully tagged.

edit: the next command works
