Neat Trick for Loading Modules with unknown Name

[Randall Smith]

I've found an easy and clean way to load and use modules that are loaded
after a program has started when the name of the module can not be
pre-determined.

modname = 'usermodname'
# load the module
exec('import ' + modname)
# alias the module
usersmod = eval(modname)

Not you can use the module like this: usermod.def
Where def is some function, class, etc. defined in the module.

Very simple. I stumbled on this for a while and even read some long,
complex solutions involving using __import__, etc. Just thought I'd share.

Long, complex?

>>> modname = 'email'
>>> mod = __import__(emai l)
>>> mod[/color][/color][/color]
<module 'email' from 'Z:\python23\li b\email\__init_ _.py'>

?
