Numbers in Python

Python handles numbers intuitively. Let us explore number types and operations.

Number Types

• Integers (int) — Whole numbers: 5, -3, 100
• Floats (float) — Decimal numbers: 3.14, -0.5

Arithmetic Operators

print(5 + 3)    # Addition: 8
print(10 - 4)   # Subtraction: 6
print(3 * 7)    # Multiplication: 21
print(15 / 4)   # Division: 3.75
print(15 // 4)  # Floor division: 3
print(15 % 4)   # Modulus: 3
print(2 ** 4)   # Exponent: 16

Type Conversion

x = int(3.9)     # 3
y = float(5)     # 5.0
z = str(100)     # "100"

Useful Functions

print(abs(-7))      # 7
print(round(3.7))   # 4
print(max(3, 7, 1)) # 7
