Python standard library: Built-in function property (Fget=none, Fset=none, Fdel=none, Doc=none)

This function is a property that sets a member of a class. The parameter fget is the property value that gets the class member , and the parameter fset is the property value that sets the class member;Fdel is the delete class member; parameter doc is the document string that sets the property. Through this function, we can implement the method of hiding the class member variable, which is the requirement of object-oriented encapsulation.

Example:

#property () class Foo:    def __init__ (self):        self._x = None    def getx (self):        return self._x    def setx ( Self, value):        self._x = value    def delx (self):        del self._x    x = Property (Getx, Setx, Delx, "I ' m the ' x ' prop Erty. ")    foo = foo () foo.x = 2000print (foo.x) del foo.x

The resulting output is as follows:
