File handling in Python is a fundamental concept that allows programmers to work with files on their system, including reading from and writing to them. Python provides built-in functions and methods that make file manipulation straightforward. The primary operations include opening a file, reading from it, writing to it, and closing it after operations are complete. Python treats files as objects, and these objects support various methods for file manipulation, making it highly flexible for data analysis and automation tasks. Files in Python can be handled using the `open()` function, which takes at least one argument—the file name—and optionally, a mode that specifies the type of operations allowed on the file. Common file modes include: 1. `"r"`: Read mode, which opens the file for reading. It raises an error if the file does not exist. 2. `"w"`: Write mode, which opens _______ ______ _____ ________ ___ ________ ______.
