Lock
Explore the fundamentals of Python's Lock object within the threading module. Understand how the acquire and release methods control access between threads, preventing race conditions and ensuring thread-safe operations. This lesson includes practical examples to demonstrate synchronization and explains common pitfalls like deadlocks.
We'll cover the following...
Lock
Lock is the most basic or primitive synchronization construct available in Python. It offers two methods: acquire() and release(). A Lock object can only be in two states: locked or unlocked. A Lock object can only be unlocked by a thread that locked it in the first place.
A Lock object is equivalent of a mutex that you read about in operating systems theory.
Acquire
Whenever a Lock object is created it is initialized with the unlocked state. Any thread can invoke acquire() on the lock object to lock it. ...
