What if a non integer number is entered in age( like 5.3 or S) Can you add a stmt to say "Please enter a whole number"?

Just wondering if there is a validation method so that if a non integer is entered the loop can repeat until it validates. We might get to this in a future topic lol.

The following would prompt until a number with only digits is entered:

strPrompt = ""

while not strPrompt.isdigit():
   strPrompt = input("Please enter a whole number ")

print(strPrompt)
