Python is a powerful language for creating and handling large datasets, files, and directories. One of the most commonly used functions in Python is removing directories, but sometimes, directories cannot be removed if they are not empty. In this article, we are going to explore how to remove a directory that is not empty in Python.
Removing directories is a crucial task performed while handling data. Directories in Python can become complex and have multiple subdirectories and files under them. However, sometimes, we encounter the error that a directory is not empty while trying to remove it. This is because Python does not allow us to remove a directory that has subdirectories or files under it.
To remove a directory that is not empty, we need a parameter to force remove the directory along with its contents. The ‘shutil’ library of Python has a function ‘rmtree’ that can remove a directory that is not empty.
Let us see how to use the ‘rmtree’ function:
import shutil
shutil.rmtree('/path/to/directory')
In this code, ‘shutil’ module is imported which is used for various high-level file operations. The ‘rmtree’ is a function used to remove a directory that is not empty by providing the path of the directory that we want to remove.
Let us now look at the parameter of ‘rmtree’ function to remove the directory:
shutil.rmtree('/path/to/directory’, ignore_errors=False, onerror=None)
In this code, we can see that the ‘rmtree’ function has two additional parameters — ‘ignore_errors’ and ‘onerror’.
The ‘ignore_errors’ parameter, when set to True, allows ‘rmtree’ to continue recursively remove the subdirectories despite errors raised by the OS if the given resource entry couldn’t be found, permission denied, or various other odd scenarios, whereas when it is False, ‘rmtree’ stops processing as soon as any error occurs while removing a file or subdirectory under given root.
The ‘onerror’ parameter specifies what to do when an error occurs while deleting the directories. By default, ‘onerror’ set to None, which appears to propagate any exception.
Let us now look at the code for handling these parameters:
import shutil
import os
def delete_directory(path):
try:
shutil.rmtree(path, ignore_errors=False, onerror=None)
print(f"Directory {path} is removed successfully")
except Exception as e:
print(f"Error occurred while deleting the directory {path} : {e}")
delete_directory("/path/to/directory")
In this code, we have created a function called ‘delete_directory’ that takes the path of the directory that we want to remove. We have used the ‘try-except’ statement, which is used to handle the errors that occur while executing the code. We have used the ‘shutil.rmtree’ function, which takes three parameters — ‘path,’ ‘ignore_errors’ and ‘onerror.’ We have set the value of ‘ignore_errors’ and ‘onerror’ to None and False, respectively. We have included an error handling message that displays when an error occurs while removing the directory.
In conclusion, by using the ‘shutil’ module in Python, we can easily remove directories that are not empty. However, we must be careful while performing this operation as it may remove all the data under the directory. We can also use additional parameters to handle errors while removing directories.

In Python, removing directories or files is a common task, but sometimes it gets challenging to remove a directory or file that has subdirectories or files under it. In such cases, we can use the ‘shutil’ module in Python to remove the directories along with the files or subdirectories present under them. The ‘shutil.rmtree()’ function is the best way to remove a directory that is not empty.
The ‘rmtree’ function takes the directory path, and with the help of ‘os’ module, it removes all subdirectories and files in it. There are two parameters that we can use with ‘rmtree’ function – ‘ignore_errors’ and ‘onerror.’ These parameters are used to make the ‘rmtree’ function more flexible and to handle any errors that may occur while removing the directory.
Additionally, we can also use the ‘os’ module to remove empty directories in Python.
Here is the code for removing empty directories:
import os
os.rmdir('/path/to/empty/directory')
In this code, we have used the ‘os’ module’s ‘rmdir()’ function, which takes the path of the empty directory we want to remove and removes the directory from the file system. However, if the directory is not empty, an error will be raised.
The above code can be used to remove empty directories in Python. We can use the ‘os.path.isdir()’ function to check if the directory is empty or not before using the ‘os.rmdir()’ function. If the directory is not empty, we can use the ‘shutil.rmtree()’ function to remove the directory and all the files and subdirectories present in it.
Moreover, we can also handle the error message while using the ‘os.rmdir()’ function. We can use a try-except block to catch the error when the directory is not empty.
Here is the code:
import os
try:
os.rmdir('/path/to/empty/directory')
print("Directory removed successfully!")
except OSError as e:
print(f"Error: {e} - directory not empty.")
In this code, the ‘try-except’ block is used to handle the OSError which is raised when the directory is not empty. In the try block, we have used the ‘os.rmdir()’ function to remove the directory, and in the except block, we have printed an error message indicating that the directory is not empty.
To sum up, in Python, removing directories and files may seem like a simple task at first glance, but sometimes it can be tricky and complicated, especially when dealing with nested directories or files or when encountering errors. However, by using the ‘shutil’ and ‘os’ modules and the ‘rmtree()’ and ‘rmdir()’ functions, we can easily remove directories and files in Python.
Popular questions
- What is the 'shutil' module in Python?
Answer: The 'shutil' module in Python is used for high-level file operations, such as copying, moving, deleting, and archiving files and directories. It provides a simpler interface compared to the 'os' module for various file handling tasks.
- What is the 'rmtree' function in Python?
Answer: The 'rmtree' function is a part of the 'shutil' module in Python, which is used to remove a directory and its contents, including all subdirectories and files under it, even if the directory is not empty.
- What are the parameters used with the 'rmtree' function?
Answer: The 'rmtree' function takes two optional parameters – 'ignore_errors' and 'onerror.' The 'ignore_errors' parameter, when set to True, allows 'rmtree' to continue removing subdirectories despite errors. The 'onerror' parameter specifies what to do when an error occurs while deleting directories.
- How can we remove empty directories in Python?
Answer: We can use the 'os' module in Python to remove empty directories. The 'os.rmdir()' function can be used to remove empty directories. However, if the directory is not empty, an error will be raised.
- How can we handle errors while removing directories in Python?
Answer: We can handle errors while removing directories in Python by using the try-except block. When an error occurs, it can be caught by the except block, which can be used to display an error message or handle the error in a different way.
