### PYTHONPATH

What is the `PYTHONPATH` we mentioned earlier? This is a list of paths on your system where Python will look for packages. Python will always look first in the working directory (the folder you're in when you start the REPL or run your program), so if your module folder is there, you can import it. You can also install your modules just like any other external modules, using a `setup.py` file. It's also possible to change or add paths to your `PYTHONPATH` list if you need to store modules elsewhere, but this isn't a very portable solution.
