Since you mention Python, I have found pdfkit[1] to be a pretty good wrapper for wkhtmltopdf. I have a document generation engine that uses it dozens of times a day. Worst part is that wkhtmltopdf in the Ubuntu repos is still compiled (when last checked) without some patch that allows it to run headlessly. I built from source, which was not too difficult.
