Create a program that will read a CSV -f or --file of exercises (default exercises.csv) and create a Workout of the Day:
$ ./wod.py
Exercise Reps
------------------ ------
Pushups 74
Hand-stand pushups 10
Squats 29
Burpees 33
The program should accept an alternate --file:
$ ./wod.py -f silly-exercises.csv
Exercise Reps
-------------------- ------
Erstwhile Lunges 18
Hanging Chads 90
Red Barchettas 36
Masochistic Eardowns 29
And should reject non-existent file arguments:
$ ./wod.py -f lkjdflkj
usage: wod.py [-h] [-f str] [-s int] [-n int] [-e]
wod.py: error: argument -f/--file: can't open 'lkjdflkj': \
[Errno 2] No such file or directory: 'lkjdflkj'
The file structure looks like this:
$ cat exercises.csv
exercise,reps
Burpees,20-50
Situps,40-100
Pushups,25-75
Squats,20-50
Pullups,10-30
Hand-stand pushups,5-20
Lunges,20-40
Plank,30-60
Crunches,20-30
The program should accept an -n or --num argument to control the number of exercises which are randomly chosen from the input file. The “Reps” value will be randomly chosen from the given low/high range in the “reps” column:
$ ./wod.py -n 2
Exercise Reps
---------- ------
Situps 83
Pullups 30
The program should accept a -s or --seed value for the random seed to ensure reproducibility:
$ ./wod.py -s 1
Exercise Reps
---------- ------
Pushups 56
Situps 88
Crunches 27
Burpees 35
As well as a -e or --easy flag to indicate that the reps should be halved:
$ ./wod.py -s 1 -e
Exercise Reps
---------- ------
Pushups 28
Situps 44
Crunches 13
Burpees 17
The program should print a usage for the -h or --help flags:
$ ./wod.py -h
usage: wod.py [-h] [-f str] [-s int] [-n int] [-e]
Create Workout Of (the) Day (WOD)
optional arguments:
-h, --help show this help message and exit
-f str, --file str CSV input file of exercises (default: exercises.csv)
-s int, --seed int Random seed (default: None)
-n int, --num int Number of exercises (default: 4)
-e, --easy Halve the reps (default: False)
Run the test suite to ensure your program is working correctly:
$ make test
pytest -xv test.py

The test suite only checks your program using well-formed input files. There are several “bad” input files provided which are not used by the test but are provided for you to try with your program. These represent several types of real-world problems you might encounter parsing delimited text files.
