Deleting Files in Python

Python provides built-in support for removing files and directories using the os module. This allows your program to manage files safely and efficiently.

Removing a File

To delete a file, first import the os module and then use the os.remove() function.

Example: Delete a File

import os os.remove("old_data.txt")

Checking File Existence Before Deletion

To avoid errors, it is a good practice to confirm that the file exists before deleting it.

Example: Safe File Deletion

import os file_name = "old_data.txt" if os.path.isfile(file_name): os.remove(file_name) print("File deleted successfully.") else: print("File not found.")

Try it Yourself

• Prevents runtime errors
• Safer for real-world applications

Deleting a Folder

To remove an empty directory, use the os.rmdir() method.

Example: Remove an Empty Folder

import os os.rmdir("temp_folder")
