While loop from 1 to infinity, therefore running forever. x = 1 while True: print("To infinity and beyond! We're getting close, on %d now!" % (x)) x += 1 · When running the above example, you can stop the program by pressing ctrl+c at the same time. As you can see, these loop constructs serve different purposes.

Here, print('Last statement') is outside the body of the loop. Therefore, this statement is executed only once at the end. If we iterate through a string, we get individual characters of the string one by one. language = 'Python' # iterate over each character in language for x in language: print(x)

The break statement in Python brings control out of the loop. ... for letter in 'geeksforgeeks': if letter == 'e' or letter == 's': break print('Current Letter :', letter) ... Explanation: break statement is used to exit the loop prematurely when a specified condition is met. In this example, the loop breaks when the letter is either 'e' or 's', stopping further iteration.

If you want to see what range() produces for debugging purposes, you can pass it to the list() function.

r/learnpython on Reddit: Struggling to understand for loops in Python
September 9, 2025 -
Hey everyone, I’m learning Python and I feel really stuck when it comes to for loops. I understand the basic syntax like:
for i in range(5):
print(i)But when I try to apply loops to real problems, I get confused. For example, looping through a list or using range with different start/stop/step values trips me up. Sometimes I don’t know when to use for item in list versus for i in range(len(list)).
It feels like I understand loops in isolation but not how to use them properly in practical code.
Can someone explain in a simple way how to think about for loops, and maybe give me some beginner-friendly challenges/exercises so I can practice the right way?
Thanks a lot!

If we stay with the example of a list, think of it this way: Imagine you have a list with elements [a,b,c] And you need to loop through the list for some action The question then is, do you need the actual elements, for example because you want to validate them or something? In that case going with the actual element in "for i in list" is the way to go. However, if you need the indexes of the items, for example for comparing or checking where in an ordered list items are, going with "for i in range(len(list))" is the way to go, as it allows you to check the current element of the list with a simple "list[i]" while being able to do something with the index itself. Ideally very often you would use something more descriptive than "i" if you need to do a bigger operation with it in order to makeit clear to the reader of your code what the selected item/index is for Please excuse my poor code formatting, I am on mobile, but I hope this helped you a little.. TLDR: It depends on use case which way to use for loops

For the most part it's a matter of convenience and practicality. Let's say you have some kids in a line, and you want to say good morning to each one. Then you would just iterate over their names. But let's say that you also want to give a present to each one, and you need to give the first gift to the first kid, the second gift to the second kid, and so on... Then you can just use the number, and you'd use the same number both for the kids and the gifts. If you're cool you can use enumerate too.
