\title{PyLuaTeX Example -- Typesetting Python Interactive Console Sessions}
\author{Tobias Enderle}
\begin{document}
\maketitle
PyLuaTeX allows you to run and typeset Python code in an interactive console
or read–eval–print loop (REPL) fashion. Very much like in an IPython session,
code is prefixed with \verb|>>>| (or \verb|...| in case of multi-line commands)
and the results are printed automatically.
Both code and output are stored in PyLuaTeX's ouput buffer and can be accessed
by \verb|pyluatex.get_last_output()|. In this way, you can adjust the typesetting
to your needs. For examples on typesetting see \verb|typesetting-listings.tex|
and \verb|typesetting-minted.tex|.
In the following example, we use the custom environment \verb|pyrepl|, which is
based on the \verb|pythonrepl| environment provided by PyLuaTeX.
\begin{pyrepl}
def fun():
print('Hello PyLuaTeX!')
3 + 1 *\
4
fun()
\end{pyrepl}
Python sessions can also be read from files:
\pyfilerepl{repl.py}
\pytypeset
