Python implementation method for searching local file information to write to a file

The example in this article describes how Python implements the search for local file information to write to a file. Share to everyone for your reference, as follows:

Main functions:

In the specified drive letter, such as D, the search for the user given a suffix name (such as: Jpg,png) related to the file, and then the search out the information (the absolute path of the relevant file), stored in the user-specified file (if the file does not exist, then set up the corresponding file)

First card look at the effect of the operation:

Run the first part of the effect:

The latter part of the run effect:

Files After writing information:
