Override installed module in import

I am currently working on a package that's nearly ready for distribution. As such, I'm trying out installing it (via setup.py) on my system. However, I also need access to the current (source code) package, e.g. for tests.

Is it possible to explicitly force importing the local package instead of the installed version? What I already tried is adding the path at the beginning of sys.paths, with no luck.

I guess this question goes into how exactly Python looks for the modules to import, and how to change the order.

EDIT : It was a silly mistake, adding at the beginning of sys.paths works. I had some other import statement elsewhere that was executed first.

  1. This is bad bad idea to do something like force importing the local package.

  2. Python3 always import the built-in modules first, and obviously you're using Python3 cause Python2 is local-first.

  3. I don't know how to solve this problem, if I were you I'd rename that file.

edit

You don't use append cause append is to the end. Use insert. Tested on my cpu. I created a requests.py in another folder.

>>> import sys
>>> sys.path.insert(0 ,"path-to-another-folder/")
>>> import requests
>>> requests.get
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'get'
>>>

If I don't do sys.path.insert(0 ,"path-to-another-folder/"), requests is imported normally.
