Here's an elaborate example: I have two modules (A.py and B.py) that
both define the function test(). My main driver prompts the user for
input and based on the input will import the module and call test() in
the imported module, which will print either "module A" or "module B"
depending on what was imported, or an error message if the input didn't
matcha module. This illustrates a complete example, but you can
simplify it really to "mymodule = __import__ (next_file)" where
next_file is a variable name
====================
--A.py
def test ():
print "module A"
--B.py
def test ():
print "module B"
--dynamicimport.py
print "Test Dynamic Import"
request = raw_input ("enter 'a' or 'b'")
modName = request.upper()
mod = None
try:
mod = __import__(modName)
except:
print "unable to import %s" % modName
if mod:
mod.test()
else:
print "Sorry, no appropriate module"
====================
