字典列表上的Python多处理 [英] Python Multiprocessing on List of dictionaries

问题描述

我有一个字典列表. list_of_dict = [{'name' : 'bob', 'weight': 50}, {'name' : 'ramesh', 'weight': 60}]

I have a list of dictionaries. list_of_dict = [{'name' : 'bob', 'weight': 50}, {'name' : 'ramesh', 'weight': 60}]

我想同时处理两个字典

该多处理池或过程应使用什么?

What should I use for this multiprocessing Pool or Process?

推荐答案

我尝试过使用Multiprocessing Pool

I have tried with Multiprocessing Pool

from multiprocessing.pool import ThreadPool as Pool

pool_size = 5 

def worker(item1, itme2):
    try:
        print(item1.get('weight'))
        print(itme2)
    except:
        print('error with item')

pool = Pool(pool_size)
items = [{'name' : 'bob', 'weight': 50}, {'name' : 'ramesh','weight': 60}]
for item in items:
    pool.apply_async(worker, (item, 'item2'))

pool.close()
pool.join()
