How do I unload (reload) a Python module?

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

The following code allows you Python 2/3 compatibility:

try:
    reload
except NameError:
    # Python 3
    from imp import reload

The you can use it as reload() in both versions which makes things simpler.
