The built-in os module has a number of useful functions that can be used to list directory contents and filter the results. To get a list of all the files and folders in a particular directory in the filesystem, use os.listdir() in legacy versions of Python or os.scandir() in Python 3.x. os.scandir() is the preferred method to use if you also want to get file and directory properties such as file size and modification date. | The built-in os module has a number of useful functions that can be used to list directory contents and filter the results.
