Q1. MINI CALCULATOR WITH PARAMETER

def add(a, b):         #a and b given in function header are called parameters

    print(a + b)

def subtract(a, b):

    print(a - b)

# taking input from user

num1 = float(input("Enter first number: "))

num2 = float(input("Enter second number: "))

# calling functions

add(num1, num2)   #num1 and num2 given in function call are arguments

subtract(num1, num2)

Q2.Store the result in a variable (using return)

def add(a, b):

    return a + b

def subtract(a, b):

    return a - b

# taking input

num1 = float(input("Enter first number: "))

num2 = float(input("Enter second number: "))

# storing result in variables

result1 = add(num1, num2)

result2 = subtract(num1, num2)

# printing results

print("Addition:", result1)

print("Subtraction:", result2)

IMPORTANT POINT

·     return sends value back to main program

·     That value can be stored in a variable and reused

·     Returned values can be stored in variables for further use in the program.
