Binary to Decimal Updated
In my other blog post ‘Binary to Decimal’, I realized what if I had put in a different number than 1 and 0. I tried putting a 2 and the code still worked. So I will be sharing an updated version, so that you can only put in either 1 or 0. Else there will be an error. # make a new function def bintodeci(num): reverse = len(num) -1 exp = 0 total = 0 for index in range(reverse, -1, -1): # if each number is either 0 or 1 else it'll print out an error. if num[index] in '01': total += int(num[index]) * (2**exp) exp += 1 else: print("Error: Invalid binary number") return None # return the value return total # In case I want to import it if __name__ == '__main__': print(f'The variable __name__ is {__name__}') answer = bintodeci("111") print(answer)
