I think this is working.... First off, 2 module files:

funcs.py
def func1():
print "I'm func1 in funcs.py"

more.py
def func2():
print "I'm func2 in 'more.py'"

and my wonderful main program:

xx.py
import funcs
def addnewfuncs(p):
x = __import__(p)
funcs.__dict__.update(x.__dict__)
funcs.func1()
addnewfuncs('more')
funcs.func2()

The first problem I had was getting import to accept a variable. It
doesn't seem to, so I used __import__(). Then, I had to remember to
assign this to a variable ... and then it appears to work just fine.

Did I miss anything in this???

You are updating with *everything* in the 'more' module, not just the
functions. This includes such things as __name__, __doc__, __file__.
Could have interesting side-effects.

One quick silly question: why do you want to do this anyway?

Sorry, *two* quick silly questions: are the add-on modules under your
control, or do you want to be able to do this with arbitrary modules?
[If under your control, you could insist that such modules had an
__all__ attribute with appropriate contents]

A third: why do you want to import into an existing namespace? Now
that you know about __import__, why just not call the functions where
they are?

Cheers,
John
