After this contribution, when using module at the root dir (maybe bad manners), the followings are expected behaviors?

(1) relative drive in sys.path -> bytecode is not put in __pycache__ folder.

>>> import sys
>>> sys.path.append('F:')  # flash device, etc...
>>> import foo
>>> foo.__file__
'F:foo.py'
>>> foo.__cached__
'F:foo.cpython-311.pyc'


(2) absolute drive in sys.path -> __pycache__ is under current dir, not absolute.

>>> import sys
>>> sys.path.append('F:\\')
>>> import foo
>>> foo.__file__
'F:\\foo.py'
>>> foo.__cached__
'F:__pycache__\\foo.cpython-311.pyc'
