Which Python PDF writing library is best?

[cored0mp]

I had some fun this weekend having a go at pdfkit with mixed results. Can anyone nominate a candidate for best PDF writing?

I am not using such right now but a buddy is and pdfkit works fine.
What do you mean by mixed results?

Hey nice to hear from you. So when I try pdfkit the from_file method it doesn't work, giving me the error:

    pdfkit.from_string(report, '/tmp/out.pdf', options=options)
  File "/usr/lib/python3/dist-packages/pdfkit/api.py", line 72, in from_string
    return r.to_pdf(output_path)
  File "/usr/lib/python3/dist-packages/pdfkit/pdfkit.py", line 156, in to_pdf
    raise IOError('wkhtmltopdf reported an error:\n' + stderr)
OSError: wkhtmltopdf reported an error:
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-service'
Error: This version of wkhtmltopdf is build against an unpatched version of QT, and does not support more then one input document.
Exit with code 1, due to unknown error

But it works with a string (using from_string), yielding a decent-looking PDF, provided that my HTML doesn't attempt any images.

I just patched my dev system and uname gives:
Linux 5.15.0-91-generic #101~20.04.1-Ubuntu SMP Thu Nov 16 14:22:28 UTC 2023 x86_64 x86_64 x86_64

Maybe I'm better off rendering in docx format and converting to PDF from there? My major constraint is that I'm trying to avoid hackish solutions. I want to stick as close to stock Ubuntu/Red-Hat as possible.

Hence both wkhtmltopdf and pdfkit as strong contenders, both of them being in the repos.
