1，作業系統命令列看系統python的庫
where python
C:\Users\augus\AppData\Local\Microsoft\WindowsApps\python.exe
>>> for item in sys.path:
... print(item)
...
C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.12_3.12.1520.0_x64__qbz5n2kfra8p0\python312.zip
C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.12_3.12.1520.0_x64__qbz5n2kfra8p0\DLLs
C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.12_3.12.1520.0_x64__qbz5n2kfra8p0\Lib
C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.12_3.12.1520.0_x64__qbz5n2kfra8p0
C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.12_3.12.1520.0_x64__qbz5n2kfra8p0\Lib\site-packages
2，如果使用了虛擬環境（系統+虛擬環境）
2.1，在pycharm的控制檯（系統+虛擬環境+專案環境）
PyDev console: starting.
Python 3.12.5 (tags/v3.12.5:ff3bc82, Aug 6 2024, 20:45:27) [MSC v.1940 64 bit (AMD64)] on win32
import sys
for item in sys.path:
print(item)

2.2，在pycharm的os控制檯
(.venv) PS C:\Users\augus\PycharmProjects\pythonProject> python
