Please note that Exercise 3 requires that you create 2 programs: my_password_module . use_my_password_module my_password_module is a container for password vandation functions that will be used by other programs. The module should contain the following validation function: validate_password() The code in validate_password() should include all code demonstrated in the Part 3 tutorial video plus additional code that implements the following requirements: 1 Password may not contain the word "password" in any case. 2 Password may not contain the word "secret" in any case Please be sure to code all strings used as regular expression patterns using Python raw strings. my_password_module should also include a main() function that will contain unit testing code. Your code should include all unit test code demonstrated in the Part 3 tutorial video plus enough additional unit test cases to fully test the additional requirements introduced above. Since your version of my password module is an enhancement of the code demonstrated in the Part 3 tutorial video, you should use the unit testing code from that video as your starting point. When you add further unit testing code, use my approach from the tutorial video as your model. When this module is run by itself (not when it is imported), the console session should look like this: Unit testing output...
