What is File Handling in Python

File handling in Python refers to the process of creating, reading, writing, and manipulating files on a computer system using Python programming language. It allows developers to interact with files, such as text files, binary files, and more, enabling them to store and retrieve data efficiently. File handling is essential for tasks like data storage, configuration management, and logging. Python provides built-in functions and libraries to perform file operations, making it easy to work with files. File handling in Python is done using built-in functions and methods provided by the language. The most common operations include: “open()”
