How can I check if string input is a number?

How do I check if a user's string input is a number (e.g., -1, 0, 1, etc.)? user_input = input("Enter something:") if type(user_input) == int: print("Is a number") else: print("Not a number") The above won't work since input always returns a string.
Simply try converting it to an int and then bailing out if it doesn't work. try: val = int(userInput) except ValueError: print("That's not an int!") See Handling Exceptions in the official tutorial.
