The TKinter library ships with Python. So I guess that would be the

there are several frameworks depending on the features you want.
This may help list some of the frameworks and help you choose:

If you can grep for the header lines you can retrieve the headers
and the line number for seeking. grep is (probably) faster than python so
I would have it be 2 steps.
1. grep > temp.txt
2. python; check if ID is in temp.txt and
r your question, you will not get more than one as an
argument. That is expected behavior.

choice = list( ast.literal_eval( choice ) )

In my experience, a generic combobox with hundreds or thousands of elements is
difficult and annoying to use. Not sure if the Tkinter version has scroll

Wouldn't that concatenate the data from each file
rather than keeping each file's data separate?
