Python Built-in Functions and Modules
Python built-ins refer to functions, types, and modules that are available by default in the Python programming language without the need for importing external libraries. Built-in functions include fundamental operations such as `print()`, `len()`, `range()`, and `type()`, which are commonly used for various tasks like outputting data, determining the length of sequences, generating sequences of numbers, and querying the type of objects. Additionally, built-in types like `int`, `str`, `list`, `dict`, `tuple`, and `set` provide fundamental data structures and operations for storing and manipulating data. Python also provides built-in modules like `math`, `random`, `os`, and `sys`, which offer additional functionality for mathematical operations, random number generation, interacting with the operating system, and accessing system-specific parameters. Understanding Python's built-ins is essential for proficient programming in Python, as they provide a foundation for performing common tasks efficiently and effectively.
