tika-python VS codequestion

At my previous job we had the same problem which we solved by using Tika. We called it on the server along with other stuff, but there is also a Python binding.

Hey, I’ve spent quite a bit of time looking at extracting text as accurately as possibly from PDFs, it’s turns out that it is not as simple as it might seem. It is especially tricky once you get a wide variety of PDFs (including PDFs with image based text or tables). While I unfortunately cannot share the code I used to extract this text, I will tell you that for what I think your doing, the best solution will require a few things. First you should pick a good module. I’ve spent a long time going over open source solutions to this and the best two I’d say are Excalibur and Apache Tika .

Tika is from Apache so yes its original code base is Java but it has bindings in other languages. Checkout Tika-Python!

The Textractor instance is the main entrypoint for extracting text. This method is backed by Apache Tika, a robust text extraction library written in Java. Apache Tika has support for a large number of file formats: PDF, Word, Excel, HTML and others. The Python Tika package automatically installs Tika and starts a local REST API instance used to read extracted data.

codequestion - Ask coding questions directly from the terminal

Woah. https://github.com/neuml/codequestion looks pretty sweet.
