How Can You Implement Multithreading in Python Effectively?

Threads in Python: Simplified Implementation

In programming, it is often desirable to execute multiple tasks simultaneously. In Python, this can be achieved using threads.

Thread Creation Using Functions

To create a thread in Python without using a subclass, you can follow these steps:

1. Import the threading module.
2. Define a function that contains the code you want to execute in the thread.
3. Pass this function as the target parameter to a Thread object.
4. Call the start() method on the Thread object to start execution.
5. Optionally, call the join() method to block until the thread finishes.

For example:

<code class="python">from threading import Thread
from time import sleep

def threaded_function(arg):
    for i in range(arg):
        print("running")
        sleep(1)


if __name__ == "__main__":
    thread = Thread(target=threaded_function, args=(10,))
    thread.start()
    thread.join()
    print("thread finished...exiting")</code>

In this script, the threaded_function is executed as a separate thread and prints "running" every second for 10 seconds. The join() method ensures that the main thread waits for the thread to complete before continuing.
