Number

Numbers in Python refer to the data type used to represent numeric values. Python provides several types of numbers, including integers, floating-point numbers, and complex numbers.

Integers are whole numbers without any decimal points. They can be positive or negative, such as 1, -5, or 0. In Python, integers have unlimited precision, meaning they can be as large or as small as the system's memory allows.

Floating-point numbers, or floats, represent real numbers with decimal points. They can be positive or negative, and can have a fractional part, such as 3.14 or -0.5. Python uses the double-precision format to store floating-point numbers.

Complex numbers, on the other hand, consist of a real part and an imaginary part. They are expressed in the form of a + bj, where a and b are real numbers and j represents the square root of -1. For example, 2 + 3j is a complex number with a real part of 2 and an imaginary part of 3.

Python provides various arithmetic operations that can be performed on numbers, such as addition, subtraction, multiplication, and division. Additionally, there are built-in functions and modules that offer more advanced mathematical operations, including exponentiation, square root, trigonometric functions, and logarithms.

Numbers in Python are versatile and widely used in various applications, from simple calculations to complex mathematical algorithms. Their flexibility and ease of use make Python a popular choice for numerical computations and scientific computing.
