Yes. Since I posted this, I tried the following:
>>> X = __import__("xml")
>>> help(X)
## seems to work kind of like "import foo as f"

I'm just in the design phase of a large implementation where many
modules - each having the same function and data member names - would
be generated outmatically and a calling application would import such
a module based on the name of the main application.
This may not prove to be the pythonesque way of doing it, but
am investigating python's particular features around this subject.
Here's a little more detail;
Let's say we have a series of executable scripts called
form1.py, form2.py, form3.py and each import a function
called 'setup()' from a common module called (!!) Common.py.
Inside of the setup() function, a call to the cgi object determines
the name of the calling application (form1,py ... etc.) and
then imports another module (automatically generated from another
process), always having the same members, composing that auto module
name from the name of the calling application: form1.py =>
form1_extra.py...... And if I have to change the algorithm that
determines the name of the module imported or the names of the
members of the modules, I could just do it in two places:
the setup() function and the application generating the auto modules
(which isn't necessarily written in python).
but like I said, I'm just thinking about this now, and am open to
alternatives.
Thanks Alan
