File Handling

Last Updated : 5th September 2025

File handling in Python is a fundamental concept that allows you to manipulate and work with files. It provides a way to create, read, write, and manipulate files on the local system.

📂 File Handling

In Python, you can work with files using the built-in open() function. The open() function takes two arguments: the file name and the mode in which you want to open the file.

The mode can be one of the following:

  • "r" (read mode): Opens the file for reading.
  • "w" (write mode): Opens the file for writing. If the file does not exist, it will be created.
  • "a" (append mode): Opens the file for appending. If the file does not exist, it will be created.
  • "r+" (read/write mode): Opens the file for both reading and writing.
  • "w+" (read/write mode): Opens the file for both reading and writing. If the file does not exist, it will be created.
  • "a+" (read/write mode): Opens the file for both reading and writing. If the file does not exist, it will be created.

Note:- After you open a file, you can perform various operations on it, such as reading, writing, and closing it.

file = open("example.txt", "r")
content = file.read()
file.close()

Don't worry ! We will cover file handling in upcoming sections

With Statement

with statement is used to open a file and automatically close it after the block is executed.You don't need to call the close() method for closing the file.

with open("example.txt", "r") as file:
  content = file.read()
