Write a program that will randomly capitalize the letters in a given piece of text a la a ransom note. The text may be provided on the command line:

$ ./ransom.py 'The quick brown fox jumps over the lazy dog.'
THe qUICk BrOWn fOX jumPS OVEr THE LAzy DOg.

Or with a file:

$ ./ransom.py ../inputs/fox.txt
THE QUicK BRown fox JuMPS OVER THe laZY dog.

Given no arguments, the program should print a brief usage:

$ ./ransom.py
usage: ransom.py [-h] [-s int] str
ransom.py: error: the following arguments are required: str

The program should accept a -s or --seed option to use as a random seed to ensure reproducibility:

$ ./ransom.py -s 1 ../inputs/fox.txt
thE QUICk BrOWn Fox jumpS OveR tHe LAzY dOg.

It should respond to -h and --help with a longer usage:

$ ./ransom.py -h
usage: ransom.py [-h] [-s int] str

Ransom Note

positional arguments:
  str                 Input text or file

optional arguments:
  -h, --help          show this help message and exit
  -s int, --seed int  Random seed (default: None)

Run the test suite to ensure your program is correct:
