I’m not new to python as a whole but I’m very bad at it however, I want to learn. I’ve tried to do some coding but I want to know what everything is actually doing rather than just reciting things online so if some of you could explain it to me as if I was like a baby that would make me really happy…

I would say an LLM tool may be more helpful in this case, just for the reactivity of the response and for an experience more tailored to your needs. That said, a while loop is concept related to control flow, they’re not a python exclusive feature and basically any programming language uses it in s…

While Loops, how do they work? while condition: code Run the code again and again while the condition is True. For example: cookies = 5 while cookies > 0: # condition is cookies > 0 print("Eating a cookie") cookies -= 1

You also have the notion of infinite loop: while True: print("ok") You would need to have a condition in the body of the loop for it to brake out of it.

[image] sji: You would need to have a condition in the body of the loop for it to brake out of it. Or use a break statement. while True: print("ok") break This prints “ok” just once. Usually, break follows an ‘if’ condition.

I think stepping through some loops with a good debugger can do wonders for a software developer’s intuition of what loops are for.

Just to add something that is not present in all languages: the condition can be also an object. In that case, bool() or len() are called implicitly if the type supports them. Usually len is supported by iterables: >>> a = [1, 2] >>> while a: ... a.pop() ... 2 1 >>> a [] This will work be…

I use while with the walrus operator := when I read binary data in set sizes: with open('video.ts','rb') as video: while packet := video.read(188): parse_packet(packet) It’s surprisingly fast and keeps your code readable. You can even go double walrus to read bigger chunks and then sp…

Both for this code:

i = 0

while i < 10:
    i = i + 1
