Python Coding challenge - Day 203 | What is the output of the following Python Code?

 

Code:

num = [1, 2, 3]

*middle, last = num

print(middle, last)

Solution and Explanation:

Let's break down the code step by step:

num = [1, 2, 3]: This line initializes a list called num with three elements: 1, 2, and 3.

*middle, last = num: This line uses a feature called "extended iterable unpacking". Here, *middle is used to capture all elements except the last one from the list num, and last captures the last element of the list.

*middle: This syntax with the * operator before a variable name is used to capture multiple elements from an iterable (like a list) into a new list. In this case, it captures the first two elements [1, 2] into the variable middle.

last: This variable captures the last element of the list, which is 3, and assigns it to the variable last.

print(middle, last): This line prints out the values of the variables middle and last.

Putting it all together, if we execute this code, it will print:

[1, 2] 3
This is because middle contains the first two elements [1, 2] from the list num, and last contains the last element 3 from the list num.
