内置的python加载模块

Question

I'm using python 3, and i have a module named "http" (mypackage.http) , and i have another module called foo, i want to load the built-in http module (not my mypackage.http module)

I can use

imp.find_module('http', sys.path[1:])

for get the built-in __ init__.py importlib path

Example:

/usr/local/Cellar/python3/3.3.2/Frameworks/Python.framework/Versions/3.3/lib/python3.3/importlib/__ init__.py

But the use of imp.find_module()/load_module() are deprecated.

how can i import this built-in http module by another way like importlib ?

project example:

• mypackage
  • _ init _ .py
  • http.py (has related http classes, etc)
  • foo.py (needs to use built-in http and not the mypackage.http)

Thanks!

Answer 1

Just use

import http

In Python 2, this wouldn't have worked if foo was in mypackage , but relative imports need to be explicit in Python 3.

If you're running the module as a script, you'll need to fix the path somehow. If mypackage is findable using the normal import mechanisms, then you can run the module with the -m switch:

python -m mypackage.foo

Otherwise, you may need to check the path and alter it manually, as well as setting __package__ so relative imports work right.
