How can I handle deadlocks in Python?

To handle deadlocks in Python, you can use the threading module's built-in features. One common approach is to use a timeout when trying to acquire a lock.

Can you give me an example of using a timeout with locks?

Sure! Here's a simple example:

import threading
import time

lock1 = threading.Lock()
lock2 = threading.Lock()

def thread1():
    with lock1:
        time.sleep(1)  # Simulate work
        if lock2.acquire(timeout=1):
            try:
                print('Thread 1 acquired lock2')
            finally:
                lock2.release()
        else:
            print('Thread 1 could not acquire lock2')

def thread2():
    with lock2:
        time.sleep(1)  # Simulate work
        if lock1.acquire(timeout=1):
            try:
                print('Thread 2 acquired lock1')
            finally:
                lock1.release()
        else:
            print('Thread 2 could not acquire lock1')

threading.Thread(target=thread1).start()
threading.Thread(target=thread2).start()

What happens if both threads can't acquire the locks?

If both threads can't acquire the locks, they will timeout and print a message indicating that they couldn't acquire the lock. This prevents them from being stuck indefinitely in a deadlock.
