While at work yesterday (small retail setting) the POS systems all crashed and left us manually writing down and calculating taxes by hand. I experimented with writing a script that takes purchases and puts them into a list, adding tax totals at the end.
I'm curious if anyone sees anything that can be improved upon/made more pythonic.
