Описание:
The math and random modules are built-in Python modules that provide functionalities for mathematical operations and pseudo-random number generation, respectively.
1. The math Module:
The math module provides access to common mathematical functions and constants. These functions are typically implemented in C and offer high performance and precision for numerical computations.
Mathematical Functions: It includes functions for operations like square root (sqrt()), exponentiation (exp(), pow()), logarithms (log()), trigonometric functions (sin(), cos(), tan()), and more.
Mathematical Constants: It also defines useful mathematical constants such as pi (math.pi) and Euler's number (math.e).
2. The random Module:
The random module provides functions for generating pseudo-random numbers and performing random selections. These "random" numbers are generated deterministically using algorithms, but appear random for practical purposes.
Random Number Generation: It offers various functions to generate different types of pseudo-random numbers, including floating-point numbers within a range (random(), uniform()), integers within a range (randint(), randrange()), and numbers from specific statistical distributions.
Random Selections: It also includes functions to perform random selections from sequences, such as choosing a random element (choice()), shuffling a sequence (shuffle()), or selecting a sample of elements (sample()).
