本文实例讲述了python使用multiprocessing模块实现带回调函数的异步调用方法。分享给大家供大家参考。具体分析如下:

multipressing模块是python 2.6版本加入的,通过这个模块可以轻松实现异步调用

from multiprocessing import Pool
def f(x):
  return x*x
if __name__ == '__main__':
  pool = Pool(processes=1)
  # Start a worker processes.
  result = pool.apply_async(f, [10], callback) 
  # Evaluate "f(10)" asynchronously calling callback when finished.
Copy after login

希望本文所述对大家的Python程序设计有所帮助。
