Python多进程同步简单实现代码

#encoding=utf8
from multiprocessing import Process, Lock
def func(lock, a):
  lock.acquire()
  print a
  lock.release()
if __name__ == '__main__':
  lock = Lock()
  workers = []
  # 创建两个进程
  for i in range(0, 2):
    p = Process(target = func, args = (lock, i))
    p.start()
    workers.append(p)
  # 等待所有的进程结束
  for p in workers:
    p.join()
