What is loop-else clause in Python?

Answer 1

Yes in Python you can have else clause associated with for loop. It activates only if the loop completed fully, without breaking from the cycle. Example:

for item in search_list:
if item == find_this:
print('found')
break
else:
print('not found')

Here the 'else' is indented at the same level as 'for' and it will only activate at the end, if the break was never encountered.

I didn't know about that. But wouldn't it cause an error when an `else` block is on a different indent level to the `if` block? For this typical search cases I'm used to utilise a boolean flag to indicate search result (found/not found).
