This Python exercise covers questions on the following topics:

 * Python for loop and while loop
 * Python list, set, tuple, dictionary, input, and output



EXERCISE 1: GIVEN TWO INTEGER NUMBERS RETURN THEIR PRODUCT. IF THE PRODUCT IS
GREATER THAN 1000, THEN RETURN THEIR SUM

 * Accept user input in Python
 * Calculate an Average in Python

Given 1:

number1 = 20
number2 = 30

Expected Output:

The result is 600

Given 2:

number1 = 40
number2 = 30

Expected Output:

The result is 70

Show Solution

def multiplication_or_sum(num1, num2):
    # calculate product of two number
    product = num1 * num2
    # check if product is less then 1000
    if product <= 1000:
        return product
    else:
        # product is greater than 1000 calculate sum
        return num1 + num2

# first condition
result = multiplication_or_sum(20, 30)
print("The result is", result)

# Second condition
result = multiplication_or_sum(40, 30)

Show Solution

def exponent(base, exp):
    num = exp
    result = 1
    while num > 0:
        result = result * base
