You’re given a Python function that manipulates a list of numbers.

Your task is to determine the output of the function when it’s called with a specific argument.

Question: Python Function

What will be the output of the following code??

def mystery_function(numbers):
    result = []
    for i in range(len(numbers)):
        if i % 2 == 0:
            result.append(numbers[i] * 2)
        else:
            result.append(numbers[i] + 3)
    return result

numbers = [1, 2, 3, 4, 5]
print(mystery_function(numbers))

Answer: A

Explanation:

The function mystery_function iterates over the list numbers and checks the index of each element:

• If the index is even, it multiplies the element by 2 and appends it to the result list.
• If the index is odd, it adds 3 to the element and appends it to the result list.

For the input list [1, 2, 3, 4, 5], the steps are as follows:

• Index 0 (even): 1 * 2 = 2
• Index 1 (odd): 2 + 3 = 5
• Index 2 (even): 3 * 2 = 6
• Index 3 (odd): 4 + 3 = 7
• Index 4 (even): 5 * 2 = 10

Therefore, the output of the function is [2, 5, 6, 7, 10].
