How do I use conditions in threading?

You can use conditions in threading by utilizing the Condition class from the threading module in Python. This allows threads to wait for a certain condition to be met before proceeding.

Can you give me an example of how to implement this?

Sure! Here's a simple example:

import threading

condition = threading.Condition()

def thread_function():
    with condition:
        print('Thread is waiting for the condition to be met.')
        condition.wait()  # Wait until notified
        print('Condition met, thread is proceeding.')

thread = threading.Thread(target=thread_function)
thread.start()

# Simulate some work in the main thread
import time
time.sleep(2)

with condition:
    print('Main thread is notifying the condition.')
    condition.notify()  # Notify the waiting thread

What does condition.wait() do?

condition.wait() makes the thread wait until it is notified. It releases the associated lock and allows other threads to acquire it.
