Python Coding challenge - Day 632| What is the output of the following Python Code?

 

Code Explanation:

1. Importing the time Module

import time

What it does:

Imports the time module, which provides time-related functions.

We will use time.sleep() to delay execution.

2. Defining the Generator Function delayed_count()

def delayed_count():

What it does:

This defines a generator function that will yield values with a delay.

3. For Loop Inside the Generator

    for i in range(2):

What it does:

Loops over the values 0 and 1 (i.e., range(2)).

4. Delay Execution with sleep

        time.sleep(1)

What it does:

Pauses the loop for 1 second before proceeding.

So each number will be yielded with a 1-second delay.

5. Yielding Values

        yield i

What it does:

This makes delayed_count() a generator.

It yields i each time the loop runs — after a delay.

6. Calling the Function and Printing Results

print(list(delayed_count()))

What it does:

Converts the generator to a list, forcing it to run.

Because list(...) consumes the generator, it triggers the function's execution.

So it:

Waits 1 second

Yields 0

Waits 1 second

Yields 1

Finally prints [0, 1] after a total of 2 seconds

Final Output (after 2 seconds delay):

[0, 1]
