If you specify a folder, you will get an IsADirectoryError error. For example: You may perform many high-level operations on files/directories by using shutil module. Type: BOOL. import pathlib def delete_folder(pth) : for sub in pth.iterdir() : if sub.is_dir() : delete_folder(sub) else : sub.unlink() pth.rmdir() # if you just want to delete dir content, remove this line where pth is a pathlib.Path instance. 2. If the file does not exist, it raises an OSError exception. Way 2: Using os.path isfile function. >>> p. remove Selecting specific files from a directory, sorting the result set, are very common needs. Maybe you need to list all files in a directory of a given type, find the parent directory of a given file, or create a unique file name that does not already exist.Traditionally, Python has represented file paths using regular text strings. File and Directory Access » | pathlib — Object-oriented filesystem paths¶ New in version 3.4. $ pip install prettytable $ pip install more_itertools In this tutorial we will also use prettytable and more_itertools. Migrating from OS.PATH to PATHLIB Module in Python 2 minute read In this article, I will go over the most frequent tasks related to file paths and show how you can refactor the old approach of using os.path module to the new cleaner way using pathlib module.. import pathlib def delete_folder(pth) : for sub in pth.iterdir() : if sub.is_dir() : delete_folder(sub) else : sub.unlink() pth.rmdir() # if you just want to delete dir content, remove this line where pth is a pathlib.Path instance.
