Python中threading.Timer()定时器实现定时任务_python

from datetime import datetime
from threading import Timer
 
 
def task():
    now = datetime.now()
    ts = now.strftime("%Y-%m-%d %H:%M:%S")
    print(ts)
 
 
def func():
    task()
    t = Timer(3, func)
    t.start()
 
 
func()

sys.setrecursionlimit(100000000)

from datetime import datetime
from threading import Timer
import threading
 
 
def task():
    now = datetime.now()
    ts = now.strftime("%Y-%m-%d %H:%M:%S")
    print(ts)
 
 
def func():
    task()
    t = Timer(3, func)
    t.start()
 
 
if __name__ == '__main__':
    for i in range(3):
        thread = threading.Thread(None, func)
        thread.start()
