Python Coding challenge - Day 1087| What is the output of the following Python Code?

 

Code Explanation:

1️⃣ Importing Module

import threading

Explanation

This line imports the threading module.

The threading module allows Python to run multiple threads (tasks) concurrently.

Threads help execute parts of a program simultaneously.

2️⃣ Defining the Function

def task():

Explanation

A function named task is created.

This function will be executed inside a separate thread.

3️⃣ Loop Inside the Function

for i in range(2):

Explanation

A loop runs 2 times.

range(2) generates numbers:

0, 1

4️⃣ Printing Values

print(i)

Explanation

Each iteration prints the value of i.

So the function prints:

0

1

5️⃣ Creating a Thread

t = threading.Thread(target=task)

Explanation

A Thread object is created.

target=task means the thread will execute the task() function.

At this point, the thread is created but not started yet.

6️⃣ Starting the Thread

t.start()

Explanation

This starts the thread.

The thread begins executing the task() function.

The function prints:

0

1

7️⃣ Waiting for Thread to Finish

t.join()

Explanation

join() tells the main program to wait until the thread finishes.

Without join(), the program might print "Done" before the thread finishes.

8️⃣ Printing Final Statement

print("Done")

Explanation

After the thread finishes, the main program prints:

Done

📤 Final Output

0

1

Done
