[Tutor] Comparison Textboxes

[taserian]

I'm attempting to gather the pieces I need for a simple project I'd like to
do for my job, but I'm having a difficult time finding something, and I'm
appealing to the hive mind at Tutor for wisdom.

My project needs to compare two or more large textboxes (each one
containing a file or a large amount of text) and point out their
differences, establishing one textbox as the canonical one to which the
other textboxes are compared. This functionality is done in many text
editors (Notepad++ can install a plug-in that allows comparison between two
files), so I would think that the code behind this is pretty common, yet I
can't seem to find any reference to it. My searches for "python text
comparison code" points to Python IDEs that include that functionality, but
no indication as to how to include it into my own code. I think I'm missing
something else to search by, but I can't determine what it is.

Does anyone have an idea of what I'm talking about, and can you point me in
the right direction?
