Please write the follwing program in Python 3. Please show all outpout.

Below are test to be designed based on the programs. Each test should return True, lese it should return false. Don't just use tst from the interactive examples. Think about what function is supposed to do do, and make sure to test not only that, but what it might do in unusual circumstanacces.

Use argparse to implement the CLI portion ofthe program so it works as shown below:

Output from the program should look like this when you use the -h help flag:

$ python HW3_test.py -h

usage: HW3_test.py [-h] [-u] [-w] [-l]

optional arguments:

-h, --hlep show this help message and exit

-u, --unique Flag to test the unique function from HW3

-w, --words Flag to test the words_containing function from HW3

-l, --len Flag to test the len_test function from HW3

If no arguments are given, the program should do nothing. Since there are only flages 9ie, no string arguments as in the lecture examples), you

will need to check the argparse documentation to see how to implement flag arguments.
