parse_me

sample1.txt through sample4.txt are receipts that came out of a subway POS and were destined for a printer. We want to parse out the contents of these receipts and store the information in a data structure. You can design any data structure you like to represent the data. parse_me.py contains the very beginnings of a program to do this. Finish the real_parse method of this program. You'll know you're on the right track if you can get some more of the unit tests passing (see below for instructions on how to run the unit tests). Or you can write your own solution in the language of your choice. If you're using parse_me.py, run it as follows:

./parse_me.py sample1.txt

or

./parse_me.py -vv sample2.txt

Expert Mode

Demonstrate your awesomeness with unit tests. We have included test_parse_me.py which contains a number of unit tests. You can run these using

unit2 discover

from the command line. You'll see that two of the tests are already passing. Maybe more if you've already completed the real_parse method. Develop unit tests to cover the parsing of the entire receipt, and for extra bonus points show us a commit history that demonstrated test-driven development.

LEGENDARY Mode

Do something useful with the credit-card info in sample2.txt and the two sub- cards in the footer of sample4.txt while still not breaking on any of the other samples.
