Generally, you can use the object None to indicate that something has
no value:

class Something(object):
    def __init__(self, a=None, b=None):
        self.a, self.b = a, b
    def dosomething(self):
        # manipulate self.a & self.b here

def main():
    s = Something("value1", "value2")
    s.dosomething()
