Python Coding challenge - Day 280| What is the output of the following Python Code?

 Step-by-Step Explanation:

Function Definition:

def square(n): 

    return n ** 2

A function named square is defined.

It takes one parameter, n.

The function returns the square of n (n ** 2).

Using map:

result = map(square, [1, 2, 3])

The map() function applies a specified function (square in this case) to each item in an iterable ([1, 2, 3]).

The result of map() is an iterator, which lazily applies the square function to each element in the list.

Execution of map(square, [1, 2, 3]):

Resulting iterator contains the values: 1, 4, 9.

Converting the Iterator to a List:

print(list(result))

The list() function is used to convert the iterator returned by map() into a list.

The resulting list: [1, 4, 9].

The print() function then outputs this list.

Final Output:

[1, 4, 9]
