监视 PI 上的两个 GPIO 引脚

Question

#import GPIO library
import RPi.GPIO as GPIO

#set GPIO numbering mode and define input pin
GPIO.setmode(GPIO.BOARD)
GPIO.setup(16,GPIO.IN)
try:
    while True:
        if GPIO.input(16)==0:
            print "Open_16"
        else:
            print "Closed_16"

finally:
    #cleanup the GPIO pins before ending
    GPIO.cleanup()

我如何修改上面的脚本来监视 2 个 GPIO 引脚 16 正在被监视如何监视引脚 16 并说引脚 33

谢谢你的帮助

#import GPIO library
import RPi.GPIO as GPIO

#set GPIO numbering mode and define input pin
GPIO.setmode(GPIO.BOARD)
GPIO.setup(16,GPIO.IN)
GPIO.setup(33,GPIO.IN)
try:
    while True:
        if GPIO.input(16)==0:
            print "Open_16"
        else:
            print "Closed_16"

        if GPIO.input(33)==0:
            print "Open_33"
        else:
            print "Closed_33"

finally:
    #cleanup the GPIO pins before ending
    GPIO.cleanup()

如果您想要两个引脚的状态之间的逻辑关系，如 AND、OR、XOR 等，请使用逻辑运算符 ( https://www.guru99.com/python-operators-complete-tutorial.html )
