Recently my old colleagues had a locker block with keypad lockers in which the now needed to store their belongings and papers with important data, instead of the old communal archive cabinet with a key.
Now I was sure these keypads were trivial to circumvent. And my conclusion is yes -- when you don't have a good lock out system that prevents several tries.
We will write a #Python #program that shows all possible 4! (4 factorial) combinatons. And explore how 3 different digits in a 4 digit code is saver!
