(Python) why is my output not reversing?

10 May 2018 by Thomas Daniels

output is always just a one-letter string (because it's inside the loop), so reversing it just gives the same string. What you need to do, is reversing the whole string before printing it: def binary_converter(num): reverse = "" while num != 0: output = num % 2 # 0 or 1 ...
