I am new in Python and I got confused about the way that "break" works in a for loop. There is an example in Python documentation( break and continue Statements ) which calculates prime numbers in range (2, 10):

Nov 15, 2016 · A break will only break out of the inner-most loop it's inside of. Your first example breaks from the outer loop, the second example only breaks out of the inner loop. To break out of multiple loops you need use a variable to keep track of whether you're trying to exit and check it each time the parent loop occurs.

Sep 20, 2016 · I am using Python 3.5, and I would like to use the break command inside a function, but I do not know how. I would like to use something like this: def stopIfZero(a): if int(a) == 0: b...

Mar 4, 2015 · break is used to end loops while return is used to end a function (and return a value). There is also continue as a means to proceed to next iteration without completing the current one. return can sometimes be used somewhat as a break when looping, an example would be a simple search function to search what in lst :

Nov 11, 2024 · Don't use while True and break statements. It's bad programming. Imagine you come to debug someone else's code and you see a while True on line 1 and then have to trawl your way through another 200 lines of code with 15 break statements in it, having to read umpteen lines of code for each one to work out what actually causes it to get to the break.

There is no way to do this from a language level. Some languages have a goto others have a break that takes an argument, python does not. The best options are: Set a flag which is checked by the outer loop, or set the outer loops condition. Put the loop in a function and use return to break out of all the loops at once. Reformulate your logic ...

Use break and continue to do this. Breaking nested loops can be done in Python using the following: for a in range(...): for b in range(..): if some condition: # break the inner loop break else: # will be called if the previous loop did not end with a `break` continue # but here we end up right after breaking the inner loop, so we can # simply break the outer loop as well break

if some_condition: ... if condition_a: # do something # and then exit the outer if block ... if condition_b: # do something # and then exit the outer if block # more code here I can think of one way to do this: assuming the exit cases happen within nested if statements, wrap the remaining code in a big else block.

Apr 6, 2021 · the break statement refers to the inner most loop level. the code below is an infinite loop: while True: for i in range(10): if i == 5: break # breaks the for, start a new iteration of the while loop To break the while loop, you may consider using some kind of flag like this

Jan 20, 2009 · Now if we add a break statement when i==4, our code will break out of the loop once i equals 4. You can use the break statement to break out of for loops, while loops and do-while loops. The break statement will only break out of the current loop.
