Python 定时器实现每5秒执行一次

import threading

import datetime

def task():
    current_time = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')
    print(f"Current time: {current_time}")

timer = threading.Timer(5.0, task)
timer.start()

import threading
import datetime

def task():
    current_time = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')
    print(f"Current time: {current_time}")

timer = threading.Timer(5.0, task)
timer.start()
