Getting a class attribute

[Roger Hansen]

Hi all.

I have a little problem here described by a simple example inspired by
the FAQ:

class Foo:
    def __init__(self, a):
        self.a = a

    def degree_sin(self, deg):
        return math.sin(deg * math.pi / 180.0)

    def degree_si2(self, deg, factor = math.pi/180.0, sin = math.sin):
        return sin(deg * factor)

    def degree_sin3(self, deg):
        return math.sin(deg * self.a * math.pi / 180.0)

    def degree_sin4(self, deg, factor = self.a * math.pi/180.0, sin = math.sin):
        return sin(deg * factor)


The question is how can I get "self.a" in degree_sin4?
