Python Coding challenge - Day 476| What is the output of the following Python Code?

 Code Explanation:

1. Define the generator function:

def gen():

    val = yield 1

    yield val * 2

This generator yields two values:

First, it yields 1.

Then, it waits for a value to be sent in, assigns it to val, and yields val * 2.

2. Create the generator object:

g = gen()

Now g is a generator object.

3. Start the generator:

print(next(g))

This starts the generator and runs it until the first yield, which is yield 1.

It outputs 1, and pauses at val = yield 1, waiting for a value to be sent into it.

Output so far:

1

4. Send a value into the generator:

print(g.send(10))

This resumes the generator and sends 10 into the paused yield expression.

So val = 10.

The next line yield val * 2 becomes yield 20.

Output:

20
