+To give the \module{timeit} module access to functions you
+define, you can pass a \code{setup} parameter which contains an import
+statement:
+
+\begin{verbatim}
+def test():
+ "Stupid test function"
+ L = []
+ for i in range(100):
+ L.append(i)
+
+if __name__=='__main__':
+ from timeit import Timer
+ t = Timer("test()", "from __main__ import test")
+ print t.timeit()
+\end{verbatim}
