Thank you folks, for your excellent answers. This is really a fantastic
place to learn python :-)

Without self it is a class attribute like static etc in C++/Java.
An instance variable is one that is unique to an instance!

Because your atribute is a class attribute:
class C:
ca = 123
print C.ca # 123
c1 = C()
print c1.ca# 123
c1.ca = 140
print c1.ca# 140
print C.ca # 123
c2 = C()
print c2.ca# 123
C.ca = 141
print C.ca # 141
print c1.ca# 140
print c2.ca
