If you need it, and of course only if your software is actually
written to handle it (contextually), there is a function to handle
that:

    https://docs.python.org/2/library/functions.html#reload
    https://docs.python.org/3/library/importlib.html#importlib.reload

I've used it in some very specific situations where you need to
change out parts of a running daemon without restarting the process,
but you really need a lot of extra care to get out of contexts
utilizing the modules being reloaded if you want the replacements to
actually be used.
