How do I remove the box around python code?

Question

I am using \usepackage{pythonhighlight} for python code and this creates a box around the code by default. Is there a way to remove the box?

\begin{python}
def f(x):
    return x
\end{python}

Doesn't look like pythonhighlight has made it possible to add additional options to the python environment.

One option is to define a new listings type environment, and allow for style adjustments using the optional argument to the new environment, and add frame=none there. See PythonA below.

If you want to remove all frames, add frame=none to the new style, as with PythonB below.

A third option is to make a new style and use \begin{lstlisting}[style=stylename].

\documentclass[border=2mm]{article}
\usepackage{pythonhighlight}
\lstnewenvironment{PythonA}[1][]{\lstset{style=mypython, #1}}{}

\lstnewenvironment{PythonB}[1][]{\lstset{style=mypython, frame=none, #1}}{}

\lstdefinestyle{Py2}{
  style=mypython,
  frame=none
  }
\begin{document}
\begin{PythonA}[frame=none]
def f(x):
    return x
\end{PythonA}

\begin{PythonB}
def f(x):
    return x
\end{PythonB}

\begin{lstlisting}[style=Py2]
def f(x):
    return x
\end{lstlisting}
\end{document}
