  1. Math Module: Mathematical Functions and Constants

    TL;DR

    The math module provides mathematical functions like sin(), cos(), sqrt(), and constants like pi and e for scientific and mathematical computations.

    Interesting!

    The math.isclose() function solves floating-point comparison issues by checking if two numbers are “close enough” rather than exactly equal, essential for robust numerical code.

  2. Built-in Functions: Python's Essential Toolkit

    TL;DR

    Python’s built-in functions like map(), filter(), zip(), and enumerate() provide powerful, memory-efficient ways to process data without explicit loops.

    Interesting!

    The any() and all() functions can short-circuit evaluation - any() returns True as soon as it finds one truthy value, making them incredibly efficient for large datasets.
