Create a Python program called ransom.py that will randomly capitalize the letters in a text. The program should take a -s|--seed argument for the random.seed to control randomness for the test suite. It should print usage when given no arguments or -h|--help.
$ ./ransom.py
usage: ransom.py [-h] [-s int] str
ransom.py: error: the following arguments are required: str
$ ./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)
The text can be given on the command line:
$ ./ransom.py -s 2 'The quick brown fox jumps over the lazy dog.'
the qUIck BROWN fOX JUmps ovEr ThE LAZY DOg.
Or in a file:
$ cat ../inputs/fox.txt
The quick brown fox jumps over the lazy dog.
$ ./ransom.py --seed 2 ../inputs/fox.txt
the qUIck BROWN fOX JUmps ovEr ThE LAZY DOg.
Hints:
- You can iterate each character in the input string with a
forloop - For each character, can use the
random.choicefunction to decide whether to force the character to upper or lower case using methods from thestrclass
