difference between input and print functions

Answer 1

classically, input requests information from the user, and print displays information back to the user

Answer 2

def main():
while true:
try:
numIn = int(input("Please enter an integer: "))
break
except ValueError:
print("I'm sorry, the value you entered is not a valid number. Please try again.")

if numIn%2 == 0:
print("The number you entered is even.")
else:
print("The number you entered is odd.")

main()

please excuse minor syntax issues...you get the idea though, right?
