Force import module from Python standard library i

问题:

I have a custom module in one of the directories in my PYTHONPATH with the same name as one of the standard library modules, so that when I import module_name, that module gets loaded. If I want to use the original standard library module, is there any way to force Python to import from the standard library rather than from the PYTHONPATH directory, short of renaming the custom module and changing every reference to point to the new name?

回答1:

The ideal solution would be to rename your module to something not in the standard library.

You can also switch absolute imports on if you're on Python 2.5+:

from __future__ import absolute_import

回答2:

Don't.

If you have accidentally chosen a standard library module name, change your module name to end the conflict.

回答3:

You can select the module you want to import with the imp module:

import imp
mymodule = imp.load_module(name, file, pathname, description)

The best way to do that is to put your project in one directory let's say "myproject" that resides on:

/home/me/myproject

Make a symbolic link to myproject directory to one of the default python paths, for example:

# ln -s /home/me/myproject /usr/local/lib/python2.7/dist-packages/myproject

Now when you want to import a module within your project just open a python interpreters.

>>> from myproject.mymodule import *

It will work like a charm.

One last thing, don't name your project the same as the ones found in the python path, so you won't have issues while importing.
