I'm really new to Python. I'm trying to import a third party module called primes.py. I have placed this module in C:\Python26\Lib (the location where I installed Python). I then have another file which is trying to import this module. The file attempting to import primes is located at C:\Python26.
In my Python file I have the following two lines:
import primes
import sys
When I run this file, I get the following error:
ImportError: No module named primes
Can anyone help me out?
Put primes.py in the lib/site-packages/ directory.
Also: no need to put your own Python files under the installation directory: I'd advise you to put them somewhere else (where it makes sense).
The module needs to be on your PYTHONPATH or in the same directory as the script, app, or module that is trying to import the module.
I'm not a Windows programmer but if you have placed the module in 'C:\Python26\Lib' and your path is set to 'C:\Python26' you need to add '\Python26\Lib' to your PYTHONPATH. I'm not certain on what the syntax would be but it should be something like 'C:\Python26;C:\Python26\Lib'. Assuming everything is the same on Windows, the subdirectories are not searched automatically.
I think a more appropriate place to put the module is to place it in 'site-packages', I don't know how this is accomplished on Windows. On *nix systems there is a script 'setup.py' that comes with the package/module, and uses 'setuptools' to build and install the package/module for you.
you probably should located this under site-packages directory or a private folder instead. Check your sys.path to understand your import paths.
