reloading my own modules

[Lowell Kirsh]

I have a driver module as well as several other modules. I am running
the driver interactively from emacs - that is, I don't restart python on
each run. I want to work it such that every time a modify the source for
one of the non-driver modules and re-run the driver, the other modules
will be reloaded. I have the following at the top of my driver module:

import dbtest, util
for module in ['dbtest', 'util']:
if module in sys.modules.keys():
reload(sys.modules[module])

Is this the best way to do it? It seems a bit verbose, but not really
all that bad. I was just wondering if there is a more standard way to do it?

Not that I'm aware of. You don't need to request the keys() of a dict in
recent versions of Python:

import dbtest, util
for module in ['dbtest', 'util']:
if module in sys.modules:
reload(sys.modules[module])

Also, since it's clear you have already imported dbtest and util, there's no
need to check in sys.modules:

import dbtest, util
reload(dbtest)
reload(util)

Hi,

Also, since it's clear you have already imported dbtest and util, there's no
need to check in sys.modules:

import dbtest, util
reload(dbtest)
reload(util)

Won't this load the modules twice on the first run? I only want to load
the modules once each time the script is run.
