This is not insightful. It describes (in a very typical padded, AI style) some generic reasons that PDFs are hard to parse (which apply just as much in any programming language), and then makes a few common suggestions for Python PDF parsing libraries that could trivially be found by anyone who needs them with a simple Web search (https://duckduckgo.com/?q=python+pdf+library), or by looking around more specialized places (e.g. https://stackoverflow.com/search?tab=votes&q=%5bpython%5d%20... , even though this is considered off-topic on Stack Overflow now). Or by asking here, for that matter.

Admittedly, PyPI's own search is quite poor for this sort of thing.
