Adding Tables and Extracting Values from Tables

[gruntfutuk]

You could represent a table as a list of lists, or a dictionary of lists, or a numpy matrix, or a dataframe in pandas, or a class, or ... well, lots of options really. It depends on what you are trying to do and the source of the data you are dealing with.

I see you picked a dictionary. Keep in mind that the keys in a dictionary must be unique, so you cannot repeat rows/columns.
