WSL の例
>>> import site
>>> site.getsitepackages()
['/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages',
'/usr/lib/python3.6/dist-packages']
>>> site.getuserbase()
'/home/wsluser/.local'
>>> site.getusersitepackages()
'/home/wsluser/.local/lib/python3.6/site-packages'
実際にインポートされるのは sys.path の場所から
>>> import sys
>>> sys.path
['', '/usr/lib/python36.zip', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload',
'/home/wsluser/.local/lib/python3.6/site-packages', '/usr/local/lib/python3.6/dist-packages',
'/usr/lib/python3/dist-packages']
-m site を使うとまとめて見れる
~> python3 -m site
sys.path = [
'/home/wsluser',
'/usr/lib/python36.zip',
'/usr/lib/python3.6',

Windows だと DLLs に .pyd ファイル
Linux は lib-dynload に .so ファイル (dyn は dynamic)
ここのフォルダは _ から始まるファイルばかり
.py ファイルからインポートされる内部モジュールばかりでユーザが直接 import するのはなさそう
Windows
>>> import site
>>> site
<module 'site' from 'C:\\Users\\winuser\\Anaconda3\\lib\\site.py'>
>>> import _tkinter
>>> _tkinter
<module '_tkinter' from 'C:\\Users\\winuser\\Anaconda3\\DLLs\\_tkinter.pyd'>
Linux
>>> import _sqlite3
>>> _sqlite3
<module '_sqlite3' from '/usr/lib64/python3.7/lib-dynload/_sqlite3.cpython-37m-x86_64-linux-gnu.so'>
