创建一个线程

1.示例代码

import time
import threading
def task(arg):
    time.sleep(2)
while True:
    num = input('>>>')
    t = threading.Thread(target=task.args=(num,))
    t.start()

创建一个线程池

1.示例代码

import time
from concurrent.futures import ThreadPoolExecutor

def task(m, n):
    time.sleep(2)
    print(m, n)

# 创建了一个线程池(最多5个线程)
pool = ThreadPoolExecutor(3)

for i in range(10):
    # 去线程池中申请一个线程,让线程执行task函数
    pool.submit(task, i, 8)

2.示例代码

import time
from concurrent.futures import ThreadPoolExecutor
def task(arg):
    time.sleep(50)
pool = ThreadPoolExecutor(10)
while 1:
    num = input('>>>')
    pool.submit(task,num)
