Question

如何在每5秒的时间间隔内执行两个函数，直到计时器停止在Python中使用线程。

e.g：

def first_func():
    print("First function")

def second_func():
    print("Second function")

Result should be like this:
-------------------------------
First Function     At starts
Second Function    5 Seconds
First Function     10 Seconds
Second Function    15 Seconds
First Function     20 Seconds
Second Function    25 Seconds
First Function     30 Seconds

And so on.

Answer 1

尝试使用多处理

def you_function1(*args, **kwargs):
    pass

def you_function2(*args, **kwargs):
    pass

from multiprocessing import Process

first_process = Process(target=you_function1)

second_process = Process(target=you_function2)

first_process.start()

second_process.start()

first_process.join()
second_process.join()

Answer 2

线程非常简单：

import threading
import time

def first_func():
    while True:
        print("First function",time.time()-start)
        time.sleep(10)

def second_func():
    time.sleep(5)
    while True:
        print("Second function",time.time()-start)
        time.sleep(10)

start = time.time()
t1 = threading.Thread(target=first_func)
t1.start()
t2 = threading.Thread(target=second_func)
t2.start()

输出：

First function 0.0
Second function 5.008664846420288
First function 10.002728939056396
Second function 15.010392904281616
First function 20.018056869506836
Second function 25.02572202682495

并行执行两个函数
