Yes.

Changing var1 does not change res.

You might like to make it a function instead:

class Test:
  var1=1
  var2=2
  def res (self):
    return self.var1+self.var2

t=Test()
t.var1=6
print t.res()

I learned in Java to give classes names with the first letter
capitalized. I find that a useful convention.
