python - 我怎样才能每小时执行一次Python代码

Question

我正在开发一个“WeatherLogger”应用程序，它将每小时/每天创建一个日志文件。这是我的代码:

import Adafruit_DHT as dht
import RPi.GPIO as GPIO
import time
import os
GPIO.setmode(GPIO.BCM)
rainsensorpin = "4"
GPIO.setup(rainsensorpin, GPIO.IN)
def log():
        print "[!] Log action executed, processing it..."
        filename = time.strftime('%d%Y-%m-%d %H:%M:%S')
        humidity, temperature = Adafruit_DHT.read_retry(sensor,pin)
        temp = "{:0.1f}*C".format(temperature)
        hum = "{:0.1f}%".format(humidity)
        state = GPIO.input(rainsensorpin)
        data = "Temp: ", temp, " Hum: ", hum, " Rain: ", state, " Date+Time: ", filename
        os.chdir("logs")
        os.mknod(filename)
        print "[+] Successfully created file: ", filename

有什么方法可以每小时或每天执行此代码吗？

如果你在Linux上，你可以使用类似5 * * * */usr/bin/wget -O - -q -t 1 http://localhost/cron.php的cron ，如果您使用的是 Windows，则使用 this链接。
