I asked that last year and the effbot replied thusly:

# import module from string
# fredrik lundh, may 2000

import imp, sys

def do_import(name, source):
   module = imp.new_module(name)
   sys.modules[name] = module
   exec source in vars(module)
   return module

script = """
def hello():
   print 'hello you too'
"""

do_import("mymodule", script)

import mymodule
mymodule.hello()
