Hi,
I found the solution to my problem:
Besides the fact I still have no clue as to how the Python name spacing
works, the code I though did stuff (the __EXEC_LIST loop) did not do as I
expected as I had already imported all of the modules in an explicit
manner.
So now I can rephrase my problem:
1) I have a program (XYZ) which displays class members in menus
2) At the time I write my program, I do not know what class members should
be in thos menus
3) So I have the class names in external files so that I can send new
modules to the 'customer' without having to release a new version of 'XYZ'
What puzzles me furher is that the 'exec' of commands such as 'sc_bc = BC()'
do work as I use them further in 'XYZ' whereas the exec of 'from xxxxxxx
import *' does not _seem_ to do anything.
Grrr! I feel more stupid every day !
Any insight ?
Thanks,
Philippe
