Python Coding Challange - Question With Answer (02161224)

 

What will the output of the following code be?

def puzzle():
    a, b, *c, d = (10, 20, 30, 40, 50)
    return a, b, c, d
print(puzzle())

A) (10, 20, [30], 40, 50)
B) (10, 20, [30, 40], 50)
C) (10, 20, [30, 40], 50)
D) (10, 20, [30, 40], 50)

Explanation:

The code involves tuple unpacking with the use of the * operator. Here's the step-by-step breakdown:

1. Unpacking the Tuple:
   The tuple (10, 20, 30, 40, 50) is unpacked using the variables a, b, *c, and d.

   • a gets the first value 10.
   • b gets the second value 20.
   • *c takes all the intermediate values as a list. In this case, *c will be [30, 40].
   • d gets the last value 50.

2. Return Statement:
   The function returns the unpacked values as a tuple: (a, b, c, d). This results in (10, 20, [30, 40], 50).

Correct Answer:

B) (10, 20, [30, 40], 50)

Key Concepts:

• Tuple Unpacking: The * operator collects multiple values into a list when unpacking.
• Order Matters: The first variable gets the first value, the last variable gets the last value, and * collects everything in between.
