How to use property function to create properties
Use property Function to create property
By using the property function we can create size
property by combining the size getter and setter.
class Rectangle(object):
def __init__(self):
self.width = 0 # from w w w.j a va 2 s .c om
self.height = 0
def setSize(self, size):
self.width, self.height = size
def getSize(self):
return self.width, self.height
size = property(getSize, setSize)
r = Rectangle()
r.width = 10
r.height = 5
print r.size
print r.size = 150, 100
print r.width
In this new version of Rectangle,
a property is created with the property function with the
accessor functions as arguments,
and this property is stored under the name size.
