Python - User input data type

Question

I\'ve written the following code in Python 3.x to validate the user\'s input:

while True:
    try:
        answer = int(input(\"Enter an integer: \"))
    except         


        

Answer 1

You can do this without relying on an exception using isdigit():

answer = input("Enter an integer: ")
while not answer.isdigit():
    print("That's not a whole number. Try again.")
    answer = input("Enter an integer: ")
answer = int(answer)

isdigit() tests to see if the input string is made up entirely of numbers that can be converted with int().
