Loop back to input if input is not number.

As the title states, how do i make function loop back to input if the input is not number?

try: count = int(input("Give me a number: ")) except ValueError: print("That's not a number!") else: print("Hi " * count)

You would have to create a loop manually using a while or for loop. try/except/else statements have no built in looping features.

A simple example would be something like this:

while True: # True is always True so the loop will go indefinitely unless you stop it manually
    try:
        count = int(input("Give me a number: "))
    except ValueError:
        print("That's not a number!") 
    else: 
        print("Hi " * count)
        break # break will stop the loop

My bad, I tried the same thing just moments ago, but my indentation was off. Thanks a lot :D
