Numbers

In Python, numbers are a core data-type essential for performing arithmetic operations and calculations. Python supports three types of numbers, including integers, floating-point numbers and complex numbers. Here’s an overview of each:

x = 5      # A positive integer
y = -23    # A negative integer
z = 0      # Zero is also considered an integer
a = 10.92 #Float
c = 4j # complex number

Sample Code for Arithmetic Operators

# Addition
a = 15
b = 4
res = a + b    # Output: 19

# Subtraction
res = a - b   # Output: 11

# Multiplication
res = a * b    # Output: 60

# Division
res = a / b   # Output: 3.75

# Floor Division
res = a // b  # Output: 3

# Modulus (%)
res = a % b   # Output: 3 (because 15 divided by 4 gives remainder 3)

# Exponentiation (**)
res = 2 ** 3   # Output: 8 (because 2 raised to the power of 3 is 8)

# Absolute Value (abs)
res = abs(-10) # Output: 10 (absolute value of -10)

# Round (round)
res = round(3.14159, 2)  # Output: 3.14 (rounds to 2 decimal places)
