Yes. I want to have only one class variable called c and a and b are
required as temporary variables to calculate the value for c.

I just found one way:
class Test:
    a = 1
    b = 2
    c = a + b
    del a,b

This one works. But I suppose there must be a way to artificially
create a new block of code, some thing like this,

class Test:
   c = None
   <<howToCreateANewNameSpace>>:
       # Objects created here are local to this scope
       a = 1
       b = 2
       global c
       c = a + b
