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:
$ make test
pytest -xv test.py
