This code attempts to match known products (supplied in the file products.txt) to listings (from the file listings.txt).
To run the full code, use python solver.py. You can also specify other files for listings, products and results - use python solver.py --help for options.
This code was written in python2, but it seems to run fine on a fresh python 3.6 installation. It uses only the standard libraries, so it should Just Work.
To test the code against a limited subset of listings, use python test.py. To add more test cases, use python generate_test_data.py.
The scriptgenerate_test_data.py selects a random listing from listings.txt and offers you the solution found by solver.py. You can either agree that it's correct, or figure out the correct solution and provide it. Either way, the new listing-product_name pair is appended to the file test_data.txt.
