File handling is an essential concept in programming that allows you to read from and write to files on your computer.

What is File Handling?

File handling refers to the process of performing operations on files stored in a computer’s file system. It allows you to:

Create new files
Read data from existing files
Write data to files
Append new data to existing files
Delete files

These operations are fundamental for storing and retrieving data in many applications.

Basic File Operations

1. Writing to a File

To create a file and write data to it, use the write_to_file function. This function takes two arguments:

filename: The name of the file to which data will be written.
content: The text data that will be written to the file.

When we call this function, it opens the file in write mode. If the file doesn’t exist, it creates a new one. If it does exist, the existing content is overwritten.

Example usage:

write_to_file('example.txt', 'This is some sample text.')
