Python property methods, static methods, class methods

Methods in the class add the following adorner

Property Method: @property Change the method to a static property of the class, without parentheses when calling. To hide the implementation of the details, for the user, the feeling is to find a dead thing to write

classFlight (object):def __init__(self,name): Self.name=namedefcheck_flight (self):Print('Checking Flight%s:status'%self.name) Status= 3returnStatus @property#as a static property of a class, it is called without parentheses. To hide the implementation of the details, for the user, the feeling is to find a write dead static properties    defFlight_status (self): status=self.check_flight ()ifStatus = =0:Print('flight got canceled ...')        elifStatus = = 1:            Print('flight is arrived ...')        elifStatus = = 2:            Print('flight has departured already ...')
