CS119 Python Programming
PJ 5 – Password Game
Please write a Python program to check a password and print all the violations of this password if any. You must print "Congratulations! Your password is very secure!" if there is no violations at all for this password. The password q is the only way to quit this password checking game.
All the possible 10 violations to be detected by your program are as follows:
You must test your game program 3 times. Your test case #1 must look exactly as follows including the data. You must also do test case #2 and test case #3 with different data of at least 7 passwords. Each test case or test run must begin with a welcome message, and must end with a thank-you message.

How to submit your Project Assignment (PJ)?
(1) Each program must be well documented with block comments and proper line comments.
The beginning of each program must have a block comment to show its author, date, and purpose.
The following is an example of block comments:
# Author: _______________ ? must use your full name here!
# Date: _______________ ? must show today’s date here!
# Purpose: _______________ ? must show the purpose of this program here!
(2) You must submit to Canvas the following two items as attachments:
(a) Your source program (for example, CS119-PJ5.py ), and
(b) Your WORD document (for example, CS119-PJ5-report .docx ) containing the listing of
your Python program, and the complete output of your 3 test runs as specified.
You must not submit a zip file to Canvas.
=========================================================================.
//You must delete everything above & including this line to make this your Word document to be submitted.
PJ 5 Report My Name: ________________
A. The following is my Python source program:
// Please copy your source program into here from your Visual Studio IDE.
// Your code here must be in color. You must not show screen prints here.
B. The following is the console output of my 3 test runs:
// One way to copy the console output is to press Ctrl+Alt+PrtScn, which is a screen print.
// Another way to copy is to use the snipping tool. To paste the image is to press Ctrl+v.
// The console display must not be too wide, otherwise it will be too hard to read once pasted.
// Please make sure your console is long enough to show all your output lines, and is readable.
// Please copy your console output and paste into here:
