PythonTeX: Fast Access to Python from within LaTeX


The LaTeX document preparation system is frequently used to create scientific documents and presentations. This process is often inefficient. The user must switch back and forth between the document and external scientific software that is used for performing calculations and creating figures. PythonTeX is a LaTeX package that allows Python code to be entered directly within a LaTeX document. The code is automatically executed and its output is included within the original document. The code may also be typeset within the document with syntax highlighting provided by Pygments.

PythonTeX is fast and user-friendly. Python code is separated into user- defined sessions, and each session is only executed when its code is modified. When code is executed, sessions run in parallel. The contents of stdout and stderr are synchronized with the LaTeX document, so that printed content is easily accessible and error messages have meaningful line numbering.

PythonTeX greatly simplifies scientific document creation with LaTeX. For example, SymPy can be used to automatically solve and typeset step-by-step mathematical derivations. It can also be used to automate the creation of mathematical tables. Plots can be created with matplotlib and then easily customized in place. Python code and its output can be typeset side by side. The full power of Python is conveniently available for programming LaTeX macros and customizing and automating LaTeX documents.
