What are some examples of thread safety in Python?
Thread safety in Python refers to the practice of ensuring that shared data is accessed by multiple threads without causing data corruption. Examples include using locks, semaphores, and thread-safe data structures.
Can you explain how to use locks for thread safety?
Sure! In Python, you can use the threading.Lock
class to create a lock. You acquire the lock before accessing shared data and release it afterward to prevent other threads from accessing it simultaneously.
What happens if I forget to release a lock?
If you forget to release a lock, it can lead to a deadlock situation where other threads are blocked indefinitely, waiting for the lock to be released.
Are there any built-in thread-safe data structures in Python?
Yes, Python's queue.Queue
is a built-in thread-safe data structure that can be used for inter-thread communication.
