Quick Answer
Python concurrency synchronization: threading.Lock for mutual exclusion, RLock for reentrant locking, Semaphore limits concurrent access, Event for thread signaling, Condition for wait/notify. For asyncio: asyncio.Lock, asyncio.Semaphore, asyncio.Event. Queue (queue.Queue or asyncio.Queue) is the safest way to share data between concurrent units - no manual locking needed.
Answer
Use locks, semaphores, events, and conditions. Prevent race conditions and ensure safe shared-resource access. Critical in multi-threaded applications.
