Python Coding challenge - Day 605| What is the output of the following Python Code?

 Code Explanation:

1. Define sub() – A Generator Function

def sub():

    yield from [1, 2]

This function is a generator.

yield from [1, 2] yields the values 1 and 2, one by one.

So calling sub() will yield:

1, then 2.

2. Define main() – Another Generator Function

def main():

    yield 0

    yield from sub()

    yield 3

This generator yields values in three steps:

yield 0

→ First value it yields is 0.

yield from sub()

→ Calls the sub() generator, which yields:

1, then 2.

yield 3

→ Finally, yields 3.

So calling main() yields:

0, 1, 2, 3

3. Print the Generator as a List

print(list(main()))

Converts the generator into a list by consuming all its values.

Final result:

[0, 1, 2, 3]

Final Output

[0, 1, 2, 3]
