python - How to use thread instance function inside a function? -

I was trying to use a thread function in the function. But my terminal says that the global name 'thread1' is not defined?

  import time import threading count = 0 square screen (threading thread): def __init __ (   
 self): threading. Thread .__ init __ (self) self.thread_stop = incorrect DRF run (self): while not self. Thread_stop: main () def stop (self): self.thread_stop = true def test (): thread 1 = screen () thread 1. Start (DEF) main (): Global thread 1, count, while true: time. Sleep (1) count = 1 if calculation & gt; = 3: thread1.stop () Print "Stop!"  
 
>  test  function:   thread1  
  def test (): global thread 1 ...   
 Otherwise, the behavior of the dragon  in thread 1  in  test  is in the form of a local variable, so it is not seen as being started in the main  thread1 .  
 approach (which seems more clear and secure):  
  import time import threading count = 0 square screen (threading thread): def __init __ (auto, Count): Threading. Thread .__ init __ (self) self.count = count def do_something (self): while true: time.sleep (1) self.count + = 1 if self.count> = 3: print "stop!" Break def run (self): self.do_something () def test (): thread1 = screen (count) thread1.start () test ()
