Frequently-Asked Questions
Which Python versions are supported?
As Matthew writes, “… the intention is for PyPDF2 to work with Python 2 as well as Python 3.” (source)
In January 2014, the main branch works with 2.6-2.7 and 3.1-3.3 [and maybe 2.5?]. Notice that 1.19–the latest in PyPI as of this writing–(mostly) did not work with 3.x.
I often merge [concatenate] various PDF instances, and my application ‘craters’ with certain files produced by {AutoCAD, my departmental scanner, …}, even though the original files display OK. What do I do now? Crucial ideas we want you to know:
All of us contend with this sort of thing. Vendors often produce PDF with questionable syntax, or at least syntax that isn’t what PyPDF2 expects.
We’re committed to resolving all these problems, so that your applications (and ours) can handle any PDF instances that come their way. Write whenever you have a problem a GitHub issue.
In the meantime, while you’re waiting on us, you have at least a couple of choices: you can debug PyPDF2 yourself; or use Acrobat or Preview or a similar consumer-grade PDF tool to ‘mollify’ [explain] your PDF instances so you get the results you are after.
