Example 1¶

>>> class Foo:
...     def __init__(self, x):
...         self.x = x
...
>>> f = Foo(10)
>>> f.x
10
>>> setattr(f, 'x', 20)
>>> f.x
20
>>> setattr(f, 'y', 10)
>>> f.y
10
>>> f.y = 100
>>> f.y
100

Example 2¶

>>> # you can dynamically add a function as a method to a class
def b(self):
    print 'bar'

class Foo:: pass

f = Foo() print dir(f) #[‘__doc__’, ‘__module__’] setattr(Foo, ‘bar’, b) print dir(f) #[‘__doc__’, ‘__module__’, ‘bar’] f.bar() #bar
