\section*{Typesetting of Code Blocks and Ouput}
\begin{pythonq}
msg = 'Hello'

print(msg)
\end{pythonq}
\pytypeset

\section*{Typesetting of Inline Code and Ouput}
Calling \pycq{print('test', end='')}\codeinline\ in Python outputs ``\outputraw''.

\begin{python}
x = 4
\end{python}
The value of \pyq{x}\codeinline\ is \outputraw.

The result of \pyq{17 + 300}$\coderaw$ is \outputraw.

\section*{Custom Environments}
You can create a custom environment for typesetting:

\newenvironment{typesetpython}
{\PyLTVerbatimEnv\begin{pythonq}}
{\end{pythonq}\pytypeset}

\begin{typesetpython}
msg = 'Custom environment'

print(msg)
\end{typesetpython}
