This is my first post on this website. This is the code for my program, which is supposed to convert a binary number entered by the user into a decimal number. For some reason, this code works fine in Python2 and outputs the correct decimal value, but either outputs a 1 or a 2 in Python3 which isn't correct. Does anyone know what's up with this code? I've tried many things but nothing seems to work. (By the way I am a beginner).
