PypTeX: the Python Preprocessor for TeX

Author: Sébastien Loisel

PypTeX is the Python Preprocessor for LaTeX. It allows one to embed Python code fragments in a LaTeX template file.

Installation

pip install pyptex

  1. You will also need a LaTeX installation, and the default LaTeX processor is pdflatex.
  2. You need a Python 3 installation.

Hello, world

Put the following in example.tex:

\documentclass{article}
@{from sympy import *}
\begin{document}
$$\int x^3\,dx = @{S('integrate(x^3,x)')}+C$$
\end{document}

The command pyptex example.tex will generate example.pdf and an intermediary pure-LaTeX file example.pyptex. The resulting PDF can be found here

  • The pyptex executable tries to locate the Python 3 executable using /usr/bin/env python3. If this is causing you problems, try python -u -m pyptex example.tex instead.

Slightly bigger examples

  • 2d and 3d plotting tex | pdf
  • Matrix inverse exercise tex | pdf
  • The F19NB handout for numerical linear algebra at Heriot-Watt university is generated with PypTeX. pdf

TeXShop

If you want to use TeXShop on Mac, put the following into ~/Library/TeXShop/Engines/pyptex.engine and restart TeXShop:

#!/bin/bash
pyptex $1
