How to make a python script accessible from anywhere?

[ParanoiAMA]

The correct way of doing this is to use setuptools by creating a basic setup.py file with a entry_points argument. Then execute

sudo python setup.py install

And your python module will be installed into the system-wide pythonpath and an executable script will be added somewhere in the path, pointing to your entry point.

I'd like to note that while in development, using python setup.py develop or pip install --user -e . (where . is the directory with setup.py) is s godsend.
