🔢 Number Data Type

Last Updated: 11th August 2025

  • In Python, numbers are used to store numeric values.
  • They can be integers, floating-point numbers, or complex numbers.
  • Numbers are immutable — you cannot change them after creation.

Hinglish Tip 🗣: Number ka matlab hai numeric value store karna, jaise 5, 3.14, ya 2+3j.

Types of Numbers

Python supports three main numeric types:

TypeExampleDescription
int10, -5Whole numbers without decimal
float3.14, -0.5Numbers with decimal point
complex2+3jNumbers with real + imaginary part

Examples:

# Integer
x = 10

# Float
y = 3.14

# Complex
z = 2 + 3j

print(x)  # Output: 10
print(y)  # Output: 3.14
print(z)  # Output: (2+3j)

# Accessing real and imaginary parts
print(z.real)  # Output: 2.0
print(z.imag)  # Output: 3.0

# Type Checking
print(type(x))  # Output: <class 'int'>
print(type(y))  # Output: <class 'float'>
print(type(z))  # Output: <class 'complex'>

💡 Quick Practice

  • Create an integer variable with value 15 and print its type.
