What is the method for 'If loop does NOT break, run code'? [duplicate]

Question

I am trying to write a for-loop to go through values, and if by the end of the loop it did not break, I want it to run some code. For example:

for i in range(10):
    if someCondition:
        break
#If the loop did NOT break, then...
doSomething()

There is a roundabout method. For example,

didNotBreak = True
for i in range(10)
    if someCondition:
        didNotbreak = False
        break
if didNotBreak:
    doSomething()

Is there a simpler method?

Answer 1

You can use an else clause on the loop.

for i in range(10):
    if someCondition:
        break
else:
    #If the loop did NOT break, then...
    doSomething()

The else clause is executed if the loop completes without hitting a break.

See https://docs.python.org/3/tutorial/controlflow.html#break-and-continue-statements-and-else-clauses-on-loops which specifies:

... a loop’s else clause runs when no break occurs
