Python Coding challenge - Day 326| What is the output of the following Python Code?

 

Explanation:

Creating Lists:

a = [1, 2, 3]: This is a list of integers.

b = [4, 5, 6]: This is another list of integers.

Using zip:

zip(a, b): The zip() function pairs elements from the two lists (a and b) together, creating an iterable of tuples:

zip(a, b)  # Output: [(1, 4), (2, 5), (3, 6)]

Each tuple contains one element from a and one from b at the same index.

Using map with a lambda Function:

map(lambda x: x[0] + x[1], zip(a, b)): The map() function applies a lambda function to each tuple in the iterable generated by zip(a, b).

The lambda function takes each tuple x (which contains two elements) and calculates the sum of the two elements:

For the tuple (1, 4), the sum is 1 + 4 = 5.

For the tuple (2, 5), the sum is 2 + 5 = 7.

For the tuple (3, 6), the sum is 3 + 6 = 9.

The result of map() is an iterable of these sums: [5, 7, 9].

Converting to a List:

list(map(lambda x: x[0] + x[1], zip(a, b))): The map() function returns an iterable (a map object), which is converted into a list using the list() function. This results in the list [5, 7, 9].

Storing and Printing:

The resulting list [5, 7, 9] is assigned to the variable result.

print(result) outputs the list to the console:

[5, 7, 9]

Final Output:

[5, 7, 9]
