If you think of "import" as "go and grab this file of code and run it"
(like PHP's include or a preprocessor #include directive), then yes,
you would expect that. But think of it, instead, as "give me access to
this feature". If that feature doesn't yet exist, Python will go and
fetch it up; but if it does, yay! You now have access, really quickly
and easily.
