Predict the output of the following code where Hari defines a function with default parameters and calls it multiple times with different arguments

def calculate_total(price, quantity=1, discount=0):
    total = price * quantity - discount
    return total

print(calculate_total(100))
print(calculate_total(100, 3))
print(calculate_total(100, 2, 50))

  1. 100\n300\n150

  2. 100\n100\n100

  3. 100\n300\n50

  4. 300\n300\n150

Show answer & explanation

Correct answer

100\n300\n150

Explanation

The function uses default parameters: quantity defaults to 1 and discount to 0. First call: 100*1-0=100. Second call: 100*3-0=300. Third call: 100*2-50=150.
