Discuss the built-in numeric data types in Python and explain their
characteristics and usage.
Ans. Python provides several built-in numeric data types that are commonly used for
numerical computations and operations. Here are the main numeric data types in Python
along with their characteristics and usage:
1. Integer (int):
Whole numbers with practically no decimal places are Integers.
Can be positive or negative, including zero.
Examples: -3, 0, 42.
Integers are used for counting, indexing, and performing arithmetic
operations.
2. Floating-Point Number (float):
Floating-point numbers represent real numbers with a decimal point.
They can have fractional parts and can be positive or negative.
Examples: -3.14, 2.718, 0.5.
Floats are used for representing continuous quantities, performing
mathematical calculations, and storing values with precision.
3. Complex Number (complex):
They have an imaginary part and real part.
They are written in the form ‘a + bj’, where a represents the real part and ‘b’
represents the imaginary part.
Examples: 2 + 3j, -1 - 2j.
Complex numbers are used in mathematical and scientific calculations
involving real and imaginary components.
