Real Python has a tutorial on How to Work With a PDF in Python. I subscribe to Real Python because I find their tutorials well-written or, in the case of video tutorials, well-presented. The focus of this tutorial is the PythonPDF module, which can get metadata from a PDF, rotate pages, merge or split a PDF, and/or encrypt it. While the tutorial mentions “extract information” it does not mean PythonPDF can get text from a PDF that does not have a text layer already embedded on its pages — you could argue that the unintuitive nature of PDFs reveals their brokenness but that’s for another time. If you want to get text where there is no text layer, but you still want to use Python, it looks like you have to turn to PDFMiner — though a quick skim of its GH page doesn’t reveal if it has OCR capabilities backed in. Sigh.
