Python's "else" clause on loops!

In Python, you can use an else clause not just with if statements, but also with loops (for and while). This might seem strange, but the else block in loops is executed only when the loop completes normally, meaning it doesn't hit a break statement.

Here's an example:

for i in range(5):
    if i == 3:
        break
else:
    print("Loop completed normally")

Enter fullscreen mode Exit fullscreen mode

In this case, since the loop breaks at i == 3, the else clause won't execute. However, if the loop finishes without breaking, the else clause will run.

This little-known feature can be handy for scenarios where you want to check if a loop completed its iteration without interruption.
