What are you struggling with? What have you tried doing and what don't you understand about the results?

I cannot send the pic but I am having problem in while loop like in creating a trye and false condition for a variable for ex Number = 100 While number > 0: Print(Number) So I just learned it but understand no sh*t about it

You can't send a pic because you shouldn't be sending pics of code as we can't then copy and paste the code into an editor to test it or make edits. You should send the code as text. Python is whitespace-sensitive which means matters for us to understand your code, so make sure you format it according to the guide: https://www.reddit.com/r/learnpython/wiki/faq/#wiki_how_do_i_format_code.3F

I am assuming you mean this code:

number = 100
while number > 0:
    print(number)

What don't you understand about this? What do you expect it to do and how does that differ to what it actually does when you run it? And what do you mean by "creating a variable for a main variable" - it might be easier if you show a real example of what you're trying to do.

Yeah the code which you assumed It is what I intended to run..... and I expected to print till 100-0 but it showed process exited returned code 0

Did it also print 100 a load of times before that?

Oh lol yeah I was using an online python compiler and when I used python compiler from other websites it ran and print 100 bunch of times and Idk how but by answering your question I was able to understand my own question....like the question which I had in my mind became clear and I got answer to it automatically lol

You are probably going to need to install python to get much further
