Hi I am trying to ask the user to input a binary number and checking to see if
the input contains 0's and 1's. If not, I want to inform the user that the input was invalid and ask them to retry.
Any help to fix my code would be greatly appreciated.
binary = int(raw_input("Enter a binary number:")) for i in range(binary): if (binary != 0 or binary != 1): print "Invalid input" binary = int(raw_input("Enter a binary number:"))
