In the Windows system, everyone's Python installation directory is different from person to person, you need to find the python installation folder in your computer

If you can't find your own Python installation path, you can try to find it by running the following command line in the Python IDE:

import sys
for i in sys.path:
    print(i)

The running results will be similar to those shown in the figure below:

The blue box refers to your Python installation directory. The path in front of the blue box varies from person to person, while the path on the right of the blue box is the same for everyone.

All you have to do is to find the folder shown in the blue box on your computer (remember: yours may not be the [C:\Users\win\AppData\Local\Programs\Python\Python37] file in the illustration folder)

Then, just put chromedriver in this folder.
