BODMAS

Python follows the BODMAS rule (Brackets, Orders, Division/Multiplication, Addition/Subtraction) to determine the order in which operators are evaluated in an expression.

Example:

result = 10 + 2 * 5 - 3
print(result)

Output:

17

In this case, the multiplication (2 * 5 = 10) is performed before the addition and subtraction, so the result is 17.

Real-world Example:

Praveen is calculating a complex expression:

result = (5 + 2) ** 2 - 8 // 3
print(result)

Output:

45

Here:

1. Brackets are evaluated first: (5 + 2) = 7
2. Exponentiation: 7 ** 2 = 49
3. Floor division: 8 // 3 = 2
4. Subtraction: 49 - 2 = 47

Few more examples

Example 1: Using Multiple Operators

a = 15
b = 6
c = a + b * 2 - (a // b)
print(f"Result of complex operation: {c}")

Output:

Result of complex operation: 22

Example 2: Real-world Scenario

# Vasanta Kumar is calculating his earnings after a raise
initial_salary = 50000
raise_percentage = 10
new_salary = initial_salary + (initial_salary * raise_percentage / 100)
print(f"Vasanta Kumar's new salary is: {new_salary}")

Output:

Vasanta Kumar's new salary is: 55000.0
