Python Coding challenge - Day 1093| What is the output of the following Python Code?

 

Code Explanation:

1️⃣ Importing the Module

import threading

Explanation

Imports the threading module.

This module allows Python to run multiple threads concurrently.

2️⃣ Defining the Function

def task():

Explanation

A function named task is defined.

This function will be executed by each thread.

3️⃣ Function Body

print("X")

Explanation

When a thread runs this function, it prints:

X

4️⃣ Loop for Creating Threads

for _ in range(3):

Explanation

Loop runs 3 times.

_ is just a placeholder variable (value not used).

So, 3 threads will be created.

5️⃣ Creating and Starting Threads

threading.Thread(target=task).start()

Explanation

A new thread is created in each iteration.

target=task → each thread runs task().

.start() immediately starts the thread.

👉 So, 3 threads run concurrently, each printing "X".

6️⃣ Printing from Main Thread

print("Done")

Explanation

This line runs in the main thread.

It prints:

Done

There is no join(), so:

Main thread does not wait for child threads.

Execution order becomes unpredictable.

Outputs

Case 1

X

X

X

Done
