Thank you! Sorry for my poor english!
Here is a example that I want to complete:
>>> import sys, new
>>> context={"name":"david", "sex":"male"}
>>> sys.modules["foo"] = new.module("foo")
>>> import foo
>>> for attr in context:
setattr(foo, attr, context[attr])
>>> def bar():
# here is a error
# import * only allowed at module level
from foo import *
print name, sex
>>> bar()
