Delete a File in Python

 

In Python, you can delete a file using the os module, which provides functions to interact with the operating system.

Steps to Delete a File:

1. Import the os module.

2. Use os.remove() to delete the file.

Syntax:

• import os

• os.remove('filename')

• filename: The name of the file you want to delete (include the file path if it's not in the same directory).

Example:

• import os

• 
  

• # Deleting a file

• file_path = 'example.txt'

• 
  

• # Check if the file exists before attempting to delete

• if os.path.exists(file_path):

•     os.remove(file_path)

•     print(f"{file_path} has been deleted.")

• else:

•     print(f"The file {file_path} does not exist.")

Explanation:

• os.remove(): Deletes the specified file.

• The os.path.exists() function is used to check if the file exists before attempting to delete it. This helps to avoid errors in case the file doesn't exist.

Handling Errors:

If the file does not exist or the user does not have sufficient permissions to delete the file, a FileNotFoundError or PermissionError will be raised. You can handle these exceptions using a try-except block.

Example with Exception Handling:

• import os

• 
  

• file_path = 'example.txt'

• 
  

• try:

•     os.remove(file_path)

•     print(f"{file_path} has been deleted.")

• except FileNotFoundError:

•     print(f"The file {file_path} does not exist.")

• except PermissionError:

•     print(f"You do not have permission to delete {file_path}.")

Alternative Method: Using os.unlink()

• os.unlink() is another method to delete a file, and it works in the same way as os.remove().

• import os

• os.unlink('example.txt')

Both os.remove() and os.unlink() essentially do the same thing: they delete a file from the filesystem.

Deleting Directories:

To delete directories, you can use os.rmdir() (for empty directories) or shutil.rmtree() (for non-empty directories).
