Python for-else

TLDR: else branch is executed if the for loop went thru all the items without break

Can be used in for loops, where the loop is search-like, i.e., it breaks on a specific condition found in the loop.

E.g.

def find(var):
    for v in range(5):
        if var == v:
            print('Found!')
            break
    else:
        print('Not found!')

find(3)
Found!

find(13)
Not found!
