Package module not found in Python 2.5, but found in 2.6

I have package structure that looks like this:

• ae
  • util

util contains a method mkdir(d开发者_StackOverflowir) that, given a path, creates a directory. If the directory exists, no error is thrown; the method fails silently.

The directory ae and its parent directory are both on my PYTHONPATH. When I try to use this method in Python 2.6, everything is fine. However, Python 2.5 gives the following error:

util.mkdir(SOURCES)
    AttributeError: 'module' object has no attribute 'mkdir'

Why is Python 2.6 able to find this module and its method with no problems, but Python 2.5 cannot?

Maybe Python 2.5 is accessing a different version of util that does not have the mkdir method.

• do you import ae.util or import util? Either ae or its parent dir should be in PYTHONPATH, but not both
• verify you have the right util module by running print util (will print the module's source file)

---

It depends where You call this method, and what Your import is. If You write:

from ae import util
util.mkdir(SOURCES)

everything should be ok.

The error occurs probably because of the difference in the import policy between Python 2.5 and 2.6.
