The imp Module

The imp module contains functions that can be used to implement your own import behavior. Example 13-6 overloads the import statement with a version that logs from where it gets the modules.

Example 13-6. Using the imp Module

import imp
import sys

def my_import(name, globals=None, locals=None, fromlist=None):
 module = sys.modules[name] # already imported?
 except KeyError:
 file, pathname, description = imp.find_module(name)
 print "import", name, "from", pathname, description
 module = imp.load_module(name, file, pathname, description)
 return module

import _ _builtin_ _
_ _builtin_ _._ _import_ _ = my_import

import xmllib

import xmllib from /python/lib/ (.py, 
, 1)
import re from /python/lib/ (.py, 
, 1)

import sre from /python/lib/ (.py, 
, 1)
import sre_compile from /python/lib/ (.py, 
, 1)
import _sre from /python/_sre.pyd (.pyd, 
b, 3)

Note that the alternative version shown here doesn support packages. For a more extensive example, see the sources for the knee module.
