So I am trying for my program to print the message "That is not an integer!" if the user inputs something that is not an integer basically, I thought this was how you would do that but apparently isn't, could anyone tell me what I am doing wrong please?

user_number = input() if type(user_number) != int: print("That's not an integer number.")

You could try to convert the input to integer with try/except:

user_number = input() try: int(user_number) except: print("That's not an integer number.")
