一日一技：Python中实现超级简单的多线程操作

import os
from multiprocessing.dummy import Pool

def get_source(path):
    with open(path, encoding='utf-8') as f:
        count = len(f.readlines())
        print(f'文件：{path}有{count}行内容')

path_list = [os.path.join('/test', x) for x in os.listdir('/test') if x.endswith('.txt')]
pool = Pool(10)
pool.map(get_source, path_list)
