   434 %%     Consider a module called \lstinline+gcd.py+ looking like this:

   435 %%     \begin{lstlisting}

   436 %% def gcd(a, b):

   437 %%    ...

   439 %% if __name__ == '__main__':

   440 %%     print gcd(10, 25)

   441 %%     \end{lstlisting}

   442 %% If this module is imported, will it print the gcd of 10 and 25?
