Write a program that will randomly scramble the middle parts of words of 3 letters or more in a given text which may come from the command line:
$ ./scrambler.py 'The quick brown fox jumps over the lazy dog.' The qiuck bwron fox jmpus over the lzay dog.
Or from an input file:
$ ./scrambler.py ../inputs/fox.txt The qucik borwn fox jpmus over the lazy dog.
The program should accept a -s or --seed value for the random seed to ensure reproducibility:
$ ./scrambler.py -s 1 ../inputs/fox.txt The qicuk bwron fox jupms over the lazy dog.
It should print a usage if provided no arguments:
$ ./scrambler.py usage: scrambler.py [-h] [-s int] str scrambler.py: error: the following arguments are required: str
And a longer usage for -h or --help:
$ ./scrambler.py -h usage: scrambler.py [-h] [-s int] str Scramble the letters of words 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 working correctly:
$ make test pytest -xv test.py ============================= test session starts ============================== ... collected 7 items test.py::test_exists PASSED [ 14%] test.py::test_usage PASSED [ 28%] test.py::test_text1 PASSED [ 42%] test.py::test_text2 PASSED [ 57%] test.py::test_file_bustle PASSED [ 71%] test.py::test_file_fox PASSED [ 85%] test.py::test_file_spiders PASSED [100%] ============================== 7 passed in 0.72s ===============================
