Hi,
I'm writing a python program to analyse and export volumetric data. To
make development and extension easier, and to make it more useful to the
public when it is released (LGPL), I would like to enable users to place
their own python files in a "user_extensions" directory. These files
would implement a common interface in order for the main program to be
able to read them and execute the necessary code.
My question is what is the best way of implementing this?
I have investigated importing them as modules, but unless the user
modifies the main program I cannot see how the main program can learn of
the existence of specific modules.
For example:
from user_modules import *
# directory 'user_modules' contains __init__.py allowing this
# From here I would need a list of the imported modules, in order to
# execute a common command on each of them, such as
for module in imported_modules:
module.initialise()
module.get_tab_window()
How do I get from the first bit to the second bit, or is there a better
way of obtaining the functionality I need?
