What is an efficient way to generate PDF for data frames in Pandas?
Well one way is to use markdown. You can use df.to_html(). This converts the dataframe into a html table. From there you can put the generated html into a markdown file (.md) (see http://daringfireball.net/projects/markdown/basics). From there, there are utilities to convert markdown into a pdf (https://www.npmjs.com/package/markdown-pdf).
One all-in-one tool for this method is to use Atom text editor (https://atom.io/). There you can use an extension, search "markdown to pdf", which will make the conversion for you.
Note: When using to_html() recently I had to remove extra '\n' characters for some reason. I chose to use Atom -> Find -> '\n' -> Replace "".
Overall this should do the trick!
