    print("me.py __name__ = ", __name__)

    # will be me when imported from another file and run
    
    if __name__ == "__main__": # True when me.py is run, 
					# False when train.py or files other than me.py are run
      hi()
      # will excecute when me.py is run
      # if __name__ == "__main__": because this line is True
