In Python, else can be used with for and while loops. The code within the else block executes once the loop has finished iterating over all items. If the loop is exited prematurely with a break statement, then the else block is not executed.
ans = '' chars = [ 'h' , 'i' , ' ' , 'm' , 'o' , 'm' ] for c in chars : ans += c else : ans += '!' print ( ans ) # hi mom! Zip protects you from out of bounds indexes If you want to iterate through an interable and compare elements to the ones next to themselves, use zip() on the iterable, and on the same interable indexed from 1.
