I want to use Boolean ( true / false ) in my python source file, but after running the application, I receive the following error:
NameError: name 'true' is not defined
The error lies on
while true:, when I am trying to make the Raspberry Pi run a HTML script when it receives input on port 17:
import RPi.GPIO as GPIO import time import os inputSignal = 17 GPIO.setmode(GPIO.BCM) GPIO.setup(inputSignal,GPIO.IN) while true: if (GPIO.input(inputSignal)): os.system("html /home/pi/index.html") else: print("No Input")
The lower-case variants are just valid free names for variables, so you could use them for whatever you want, e.g.
true = False (not recommended ;P).
