python命令安排12.00h到13.30h之間的時間窗口

Question

我想編寫一個腳本，

如果在12.00h和13.30h的時間內輸入高電平，它應該執行腳本。

如果輸入爲高電平且時間在12.00h-13.30h之外，則腳本不應執行。 我用下面的代碼嘗試了它，但它不起作用，解決方案是什麼？

#!/usr/bin/python 



import datetime 
import subprocess 
from subprocess import Popen 
import pifacedigitalio 
from time import sleep 
pfd = pifacedigitalio.PiFaceDigital() # creates a PiFace Digital object 
testprocess = None 
now = datetime.datetime.now() 

if now.hour == 12 or (now.hour == 13 and now.minute <= 30): 
    print(True) 
else: 
    print(False) 

    if pfd.input_pins[0].value == 1 and not testprocess: 
     sleep(2) 
     subprocess.Popen(["/bin/myscript"]) 
     sleep(5) 
     testprocess = Popen(["/bin/myscriptxy"]) 

     if pfd.input_pins[0].value == 0: 
      if testprocess: 
       testprocess.kill() 
       testprocess = None 
       sleep(5) 
       subprocess.Popen(["/bin/myscript"]) 
     sleep(1)

datetime.datetime是方式比strftime的工作更加方便。

import datetime 
now = datetime.datetime.now() 
if now.hour == 12 or (now.hour == 13 and now.minute <= 30): 
    print(True) 
else: 
    print(False)
