How to create PDF file in Python and put LaTeX data?

Question

I need to create pdf file with some LaTeX data. What I have:

min_latex = (r"\documentclass{article}"
         r"\begin{document}"
         r"Hello, world!"
         r"\end{document}")

from latex import build_pdf

# this builds a pdf-file inside a temporary directory
pdf = build_pdf(min_latex)

# look at the first few bytes of the header
print bytes(pdf)[:10]

with open('temp.pdf', 'wb+') as f:
    f.write(pdf)

But I have the following error message:

File "temp.py", line 18, in <module> f.write(pdf) TypeError: argument 1 must be convertible to a buffer, not Data

@Kartoch here's error:Traceback (most recent call last): File "temp.py", line 18, in <module> f.write(pdf) TypeError: argument 1 must be convertible to a buffer, not Data — Denis Waleev

pdf is not a string - you have to invoke one of its methods to save it:

pdf.save_to("/tmp/foo.pdf")

In general, it's a good idea to go into the interactive interpreter and paste in your program up to including the pdf = ... line. Then you can say help(pdf) to find out what you can do with that object.
