In Python, the first argument of an instance method is the instance on
which it has to operate [1]. IOW, your problem is with the definition of
calculate(). You want:
class DontKnowWhat(object):
def calculate(self, data):
# code here
[1] you don't have to pass this argument - this will be handled by
Python - but you need to declare it.
