Python Coding challenge - Day 602| What is the output of the following Python Code?

 

Code Explanation:

1. Defining a Generator Function values

def values():

    for i in range(10):

        yield i

This is a generator function.

It loops over numbers from 0 to 9 (via range(10)).

yield i makes it a generator, which produces values one at a time on demand instead of all at once.

So this function, when called as values(), returns a generator that yields:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9

2. Filtering Even Numbers

filt = filter(lambda x: x % 2 == 0, values())

filter(function, iterable) keeps items from the iterable for which the function returns True.

Here, the function is lambda x: x % 2 == 0, which checks if a number is even.

So, only the even numbers from the generator values() will be kept.

This creates a filtered iterator with values:

0, 2, 4, 6, 8

3. Converting to a List and Printing

print(list(filt))

This forces evaluation of the filter object by converting it to a list.

It prints the list of even numbers produced from the generator.

Final Output

[0, 2, 4, 6, 8]
