t = timeit.Timer("foo()")To this:

With Python 3, you can use globals=globals()
t = timeit.Timer("foo()", globals=globals())From the documentation:
Another option is to pass
globals()to theglobalsparameter, which will cause the code to be executed within your current global namespace. This can be more convenient than individually specifying imports
