You can have class variables, but they're not exactly what I'd call
"static" and they certainly aren't constant.

class foo:
  bar = 2
  def __init__(self):
    self.baz = 3

f = foo()

f.bar is a class variable; f.baz is an instance variable.  Note that you
can run into problems if you're not careful because of the way scoping
rules work.
