从导入的模块导入功能

Question

I have a module with a long name. I want to import some functions from it, using from ... import ... syntax. I tried to make these imports shorter, using import ... as ... trick, but it didn't work. Why this example doesn't work?

>>> import long_named_module as spam
>>> from spam import func
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named spam

Answer 1

The best way to do that is:

import long_named_module as spam
func = spam.func

Answer 2

from long_named_module import func1, func2, func3
