I've had a bit of difficulty working the equations assigned in digital logic that are designated in base two, so I coded this up to acquaint myself with binary.

bin2dec.py

import random

while True:
    decivalue = random.randrange(0,99)
    binavalue = bin(decivalue)[2:]

    answer = int(input("What is " + binavalue + " in base ten? "))

    if answer == decivalue:
        print("..hooray! :D")
    else:
        print("..try again.. :<")
