Question

I'm writing python code in my latex file, but it contain some Arabic texts when I write it using listings in python the Arabic words don't appear!

\documentclass{article}
\usepackage{listings}
\begin{document}
\begin{lstlisting}
 if(len(tokens[c5]) >= 3):
    if (tokens[c5][0] == 'ان' and
    pos_tags[c5][1] == 'verb' and
    tokens[c5][1] != 'يكون' and
    tokens[c5][2] == 'النظام' or 
    tokens[c5][2] == 'التطبيق' or
    tokens[c5][2] == 'البرنامج'):
        NF_CF[i] += 53.33
        NF_Score[c5] +=1
\end{lstlisting}
\end{document}
