There is the reload() function, but it has pitfalls. Objects referenced from
without the module are not updated:
>>> open("tmp.py", "w").write("""
... def f(): print "version one"
... """)
>>> import tmp
>>> tmp.f()
version one
>>> g = tmp.f
>>> open("tmp.py", "w").write("""
... def f(): print "version two"
... """)
>>> reload(tmp)
<module 'tmp' from 'tmp.py'>
>>> tmp.f()
version two
>>> g()
version one
