Python Coding challenge - Day 697| What is the output of the following Python Code?

 Code Explanation:

1) def gen():

Defines a generator function called gen.

A generator uses yield instead of return, allowing it to pause and resume execution.

2) Inside gen()

x = yield 1

yield x + 2

First yield 1 → when the generator is started, it will output 1.

Then, it pauses and waits to receive a value via .send().

That received value is assigned to variable x.

Finally, it yields x + 2.

3) g = gen()

Creates a generator object g.

At this point, nothing has run inside gen() yet.

4) print(next(g))

next(g) starts execution of the generator until the first yield.

At the first yield, 1 is produced.

The generator pauses, waiting for the next resume.

Output:

1

5) print(g.send(5))

send(5) resumes the generator and sends 5 into it.

That 5 is assigned to x.

Now generator executes the next line: yield x + 2 → yield 5 + 2 → yield 7.

Output:

7

Final Output

1

7
