CSS 220 Module 1 Homework

Module 1 Submission:

· This document with answers to given questions

· Two python programs created for Part 2 a. and b.

Download the following Python programs:

allPermutations.py

allPermutationsSetLength.py

allCombinationsSetLength.py

allCombinationsUnsorted.py

allCombinationsWithRepition.py

Before executing each one, predict what the output will be.

Part 1: For each one, record your predicted outcome and the observed outcome.

allCombinationsSetLength.py

allCombinationsUnsorted.py

allCombinationsWithRepition.py

Part 2: You are creating a password generator that will create all possible passwords meeting a certain criterion. To do this you will edit the Python program allPermutationsSetLength.py to print out the total number of passwords ( not all possible passwords because it will take a huge amount of time to run the program! ) for the following criteria:

a. Password must be 8 characters long. Can be comprised of any arrangement of numbers and letters. How many potential passwords can be created? Explain/show your work. Hint: Check out the factorial function in Python.

b. Password must be 8 characters long. Can be comprised of any arrangement of numbers, letters, and the following four special characters (!, $, *, _). How many potential passwords can be created? Explain/show your work. Hint: Check out the factorial function in Python.
