You can do something like this:
mymodule = types.ModuleType("mymodule", "Optional Doc-String")
with file('funcs.py') as f:
txt = f.read()
exec txt in globals(), mymodule.__dict__
sys.modules['mymodule'] = mymodule
Note that you shouldn't exec untrusted code.
You might also look at the __import__ funciton, which can import by python path.
You might also look at the imp module.
