Python Gets the list of all file names in the specified directory

The example in this article describes how Python gets all the list of file names in the specified directory. Share to everyone for your reference. The implementation method is as follows:

This Python code implements the ability to get a list of file names that can be used to specify the characters contained in the file to facilitate the extraction of a particular type of file name list:

You can install Wlab online using PIP
