hidden attribute

[adewes]

An attribute and a method of a class share the same name. Give unique
names to the two objects or else Python will raise a
TypeError: object is not callable error at runtime. Python raises the
error because the name is associated to the attribute, so when you
insert parentheses after the name, Python actually tries to call the
attribute (although you were trying to call the function).

Modify the names

Per Python style conventions, the author modified his Rectangle class
by deleting the area method. Whenever a module needs to access the
area attribute of a Rectangle instance, the module can just access
the area attribute directly. This also suppresses the
Attribute hides this method error.

class Rectangle:
    def __init__(self, width, height):
        self.width = width
        self.height = height
        self.area = width * height
    # deleted area method from here

r = Rectangle(3, 4)
print r.area  # access the attribute directly now
