How do I unload (reload) a Python module?

Question

I have a long-running Python server and would like to be able to upgrade a service without restarting the server. What\'s the best way do do this?

if foo.py          


        

Answer 1

For those like me who want to unload all modules (when running in the Python interpreter under Emacs):

   for mod in sys.modules.values():
      reload(mod)

More information is in Reloading Python modules.
