Hi, I made a program called binary/denary convertor. Can anyone tell me about how I could stop the user entering a binary number with more than 8 numbers or 8 bit by repeating the question over and over until they do enter a correct binary number( 8-bit or less) Here is the code. I started off by entering 'len' function.
def add_binary_numbers(num1, num2): return num1 + num2 num1 = int(input('please enter the first 8 bit binary number: '),2) if len(num1) > 8: print("please enter an 8 bit binary number") return int(num1,2) num2 = int(input('please enter the second 8 bit binary number: '),2) result = add_binary_numbers(num1, num2) print('the result is', bin(result)[2:]) Thanks, Ghadir _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
