[Tex/LaTex] Default value for basicstyle in lstlisting

fontslistings

I have most of the code in Python, which renders very nice with this simple configuration of lstlisting

At a certain point I have to include an XML file, so I switched to language=XML but it renders ugly with the default charset so I added also basicstyle=\ttfamily. Now I don't know how to switch back to default style after that.

\documentclass{article}
\usepackage{listings}
\lstset{tabsize=2, language=Python, breaklines=true, 
     breakatwhitespace=true,  xleftmargin=.25in}
\begin{document}

%some python listings here

%XML listing
\lstset{language=XML, basicstyle=\ttfamily}
\begin{lstlisting}
    <XML></XML>
\end{lstlisting}

%what do I put here?

%python listings again
\begin{lstlisting}
    for i in python:
        pass
\end{lstlisting}
\end{document}
