This produces the following output: An easier way to list files in a directory is to use os.scandir() or pathlib.Path(): Using os.scandir() has the advantage of looking cleaner and being easier to understand than using os.listdir(), even though it is one line of code longer. An application program (software application, or application, or app for short) is a computer program designed to carry out a specific task other than one relating to the operation of the computer itself, typically to be used by end-users.
