根据CPU内核创建多进程

 

 

from multiprocessing import Pool
import psutil

cpu_count = psutil.cpu_count(logical=False)  #1代表单核CPU，2代表双核CPU



pool = Pool(processes=cpu_count)
for i in range(2, sht.range('A2').expand('table').rows.count+1):

    pool.apply_async(word_all,(i,))  # 使用元祖类型传参
pool.close()  # 关闭进程池，不再接受新的进程
pool.join()  # 主进程等待子进程结束
