Python多线程使用方法-threading

1：基本使用方法

import threading
import time


def a():
    for secs in range(14, 0, -1):
        print('A倒计时:', secs)
        time.sleep(1)

def b():
    for secs in range(14, 0, -1):
        print('B倒计时:', secs)
        time.sleep(1)

t = threading.Thread(target=a)
s = threading.Thread(target=b)
t.start()  # 启动线程，即让线程开始执行
s.start()  # 启动线程，即让线程开始执行

2: 遇到的坑【asyncio - await】
async await 内使用办法

async def saySorry():
    for secs in range(14, 0, -1):
        print('倒计时:', secs)
        time.sleep(1)
def between_callback():
    loop = asyncio.new_event_loop()
    asyncio.set_event_loop(loop)
    loop.run_until_complete(saySorry())
t = threading.Thread(target=between_callback)
t.start()  # 启动线程，即让线程开始执行
