Python File I/O

Python File I/O (Input/Output) refers to the built-in mechanisms in Python for reading from and writing to files on a computer's storage system. It involves using functions and methods to open, manipulate, and close files, supporting various modes like read, write, and append. This concept is essential for handling data persistence, configuration files, logs, and data processing tasks in Python applications.
