Hi,
Following is my code:
#############################################
class Animal():
flag = True
print flag
def __init__(self,name):
self.name <http://self.name> = name
print self.name <http://self.name>
def walk(self):
print "I am walking"
if __name__ == '__main__':
test = Animal('boxer')
test.flag = False
If you really want the flag to be a class attribute rather than an
instance one you should set it using the class name. So instead of
test.flag use
Animal.flag = False
That works inside the class methods too.
By setting test.flag you are creating a new instance level attribute
that exists only within the test instance. That's legal Python
but usually its not a good idea to have different instances of
the same class having different attributes.
>>> class C:
... f = True
... def g(self): self.f = 42
...
>>> c = C()
>>> c.f
True
>>> c.g()
>>> c.f
42
>>> C.f
True
>>> d = C()
>>> d.f = 66
>>> d.f
66
>>> C.f
True
>>>
