26. Concurrency Patterns

Python supports various concurrency patterns.

Examples​

  • Producer-consumer queues
  • Futures for deferred results
  • Thread and process pools

Example with Queue​

import threading, queue

q = queue.Queue()

def worker():
    while True:
        item = q.get()
        if item is None: break
        print("Processing", item)
        q.task_done()

thread = threading.Thread(target=worker)
thread.start()
q.put(1)
q.put(None)
thread.join()

Wrap-Up​

Concurrency patterns help manage coordination between tasks.
