Python Coding challenge - Day 321| What is the output of the following Python Code?

 

Code Explanation:

Input List:

numbers = [1, 2, 3, 4, 5, 6, 7, 8]

This line creates a list called numbers containing the integers from 1 to 8.

Filter Function:

even_numbers = list(filter(lambda x: x % 2 == 0, numbers))

filter(function, iterable):

filter is a built-in Python function that applies a given function to each item in an iterable (like a list). It keeps only the items for which the function returns True.

lambda x: x % 2 == 0:

This is an anonymous function (lambda function) that takes an input x and checks if it is even.

The condition x % 2 == 0 checks if the remainder when x is divided by 2 is 0, which is true for even numbers.

Result of filter:

The filter function applies the lambda to each element in the numbers list and filters out the even numbers.

list() Conversion:

filter returns a filter object (an iterator), so it is converted to a list using list().

Printing the Result:

print(even_numbers)

This prints the list of even numbers that were filtered.

Output:

[2, 4, 6, 8]
