Python queries Windows files

It's okay to use Python to write a program that queries the Windows character file

Code:

Some instructions for use:

1. Find the file name using the full file name and suffix

2. Use the full file name

3. Use partial file name information

4. Find file name information through the contents of the files

There are more than a few methods
