For some definition of "always"...
I don't know about "best", but you can do this:
1. In your .bashrc file, or equivalent, set the environment
variable PYTHONPATH:
export PYTHONPATH='./;$PYTHONPATH'
* * *
If you need this to be site-wide, rather than per person, another
possibility, untested, would be to get your site administrator to create a
sitecustomize.py file. Suppose your Python is installed in
/usr/local/lib/python3.5/
Get your site admin to create the following file:
/usr/local/lib/python3.5/site-packages/sitecustomize.py
containing the following code:
import sys
if './' not in sys.path:
sys.path.insert(0, './')
* * * *
Alternatively, a per-user solution is to create your own usercustomize.py
file, containing the same code as above.
By default, the per-user site packages directory will be:
# Unix:
~/.local/lib/pythonX.Y/site-packages
# Mac:
~/Library/Python/X.Y/lib/python/site-packages
# Windows:
%APPDATA%\Python\PythonXY\site-packages
where X Y are the major and minor version numbers, e.g. 3 5.
See the documentation for the site module for more detail:

enough, things got worse.
