title: AssertionError: group argument must be None for now python
body: <p>i m using PIR sensor to find out intruder is present or not. if intruder is present it will go to sleep for 1 min now i have to reset sleep time, for this i m using thread but it shows assertion error, help me out, below is my code.</p>
  
  <pre><code>from threading import Thread, Event
  import time
  
  import RPi.GPIO as GPIO
  
  
  class MyThread(Thread):
      def __ini(self, timeout=60):
          self.intruder_spotted = Event()
          self.timeout = timeout
  
          self.daemon = True
  
      def run(self):
          while True:
              if self.intruder_spotted.wait(self.timeout):
                  self.intruder_spotted.clear()
                  print("Intruder")
              else:
                  print("No intruder")
