Introduction

This lesson is part of our complete Python course for beginners. In this lesson, you will learn file handling in Python and how to read from and write to files.

Understanding file handling in Python for beginners is important because real-world applications need to store and retrieve data.

What is File Handling in Python?

File handling in Python allows you to create, read, write, and manage files on your system.

Opening a File

You can open a file using the open() function.

Example:

file = open(“data.txt”, “r”)

Reading a File

read()

file = open(“data.txt”, “r”)
print(file.read())

readline()

file = open(“data.txt”, “r”)
print(file.readline())

Writing to a File

write()

file = open(“data.txt”, “w”)
file.write(“Hello Python”)

File Modes in Python

• r (read)
• w (write)
• a (append)
• x (create)

Closing a File

Always close the file after use.

file.close()

Using with Statement (Best Practice)

with open(“data.txt”, “r”) as file:
print(file.read())
