Function to import module to namespace

[bvdp]

Is it possible to do this from a function: import a module and append
the defs in that module to an existing module/namesapce.

So, in my code I have something like:

# main code
import mods

def loadmore(n):
import_module(n, mods)

.....
# end of main

this will permit the addition of the the stuff in file 'n.py' to 'mods'.

Assuming that foo1() is defined in newmod, I should now be able to do
something like mods.foo1().

Thanks.

You can dynamically add objects to a module:

>>import os
os.foo = 'bar'
os.foo

'bar'

>>setattr(os, 'foo2', 'bar2')
os.foo2

'bar2'

and for the loading part you can use the __import__ builtin or maybe execfile
(see the 'built-in functions' chapter of the library reference for more about
these).

Do you mean something like this?

Yes, I think that's what I might need. I'll give it a go in my code and
see if that does work.

Thanks.
