saving my *.py files

[snippsat]

Can use site module.
Make a file sitecustomize.py in site-packages folder.

import site
site.addsitedir('C:/py_files')

Now will py_files folder be permanently added to sys.path

For one session can use append to sys.path.append

>>> import sys
>>> sys.path.append('C:/foo')
>>> sys.path
['',
 ... all other dir in sys.path
 'C:\\foo',
 'C:\\py_files',
 ]
