3. Interview question 3: How to temporarily set the search path for Python modules.

Part III — Analysis:

Interview question 1: Several ways to set the search path for Python modules:

1. Set the PYTHONPATH environment variable: Click on the button to the left of the PyCharm run button and select Edit Configurations… “, and then click the three points on the right of Environment variables to open and add. Write PYTHONPATH in Name and the address of the module to be imported in Value.
2. Add a.pth file: Open python’s root directory in the console, such as Linux, and create a.pth file in the python package directory, where vi writes the address of the module to be imported. How it works: Python scans files with a. PTH suffix (if any) at runtime and automatically adds the path to sys.path.
3. Path: import sys sys.path.append(‘ path ‘)
4. If pyCharm is used, you can set the search path directly: right-click the module you want to import, click the Mark Derectory as option, click the first one, and make it the Python source root.

Several ways to permanently set the python module search path and use it:
