Shutil module in Python provides many functions of high-level operations on files and collections of files. It comes under Python’s standard utility modules. This module helps in automating the process of copying and removal of files and directories.
shutil.rmtree() is used to delete an entire directory tree, path must point to a directory (but not a symbolic link to a directory).
Syntax: shutil.rmtree(path, ignore_errors=False, onerror=None)
Parameters:
path: A path-like object representing a file path. A path-like object is either a string or bytes object representing a path.
ignore_errors: If ignore_errors is true, errors resulting from failed removals will be ignored.
oneerror: If ignore_errors is false or omitted, such errors are handled by calling a handler specified by onerror.
Example 1: Suppose the directory and sub-directories are as follow.
# Parent directory:
# Directory inside parent directory:
# File inside the sub-directory:
We want to remove the directory Authors. Below is the implementation.
Python3
# Python program to demonstrate # shutil.rmtree() import shutil import os # location location = "D:/Pycharm projects/Lazyroar/" # directory dir = "Authors" # path path = os.path.join(location, dir ) # removing directory shutil.rmtree(path) |
Output:
Example 2: By passing ignore_errors = False.
Python3
# Python program to demonstrate # shutil.rmtree() import shutil import os # location location = "D:/Pycharm projects/Lazyroar/" # directory dir = "Authors" # path path = os.path.join(location, dir ) # removing directory shutil.rmtree(path, ignore_errors = False ) # making ignore_errors = True will not raise # a FileNotFoundError |
Output:
Traceback (most recent call last):

with os.scandir(path) as scandir_it:
FileNotFoundError: [WinError 3] The system cannot find the path specified: ‘D:/Pycharm projects/Lazyroar/Authors’
Example 3: By passing onerror.
In onerror a function should be passed which must contain three parameters.
- function: function which raised the exception.
- path: path name passed which raised the exception while removal
- excinfo: exception info raised by sys.exc_info()
Below is the implementation.
Python3
# Python program to demonstrate # shutil.rmtree() import shutil import os # exception handler def handler(func, path, exc_info): print ( "Inside handler" ) print (exc_info) # location location = "D:/Pycharm projects/Lazyroar/" # directory dir = "Authors" # path path = os.path.join(location, dir ) # removing directory shutil.rmtree(path, onerror = handler) |
Output:
Inside handler
(, FileNotFoundError(2, ‘The system cannot find the path specified’), )
Inside handler
(, FileNotFoundError(2, ‘The system cannot find the file specified’), )
