short answer: change your method declarations to:

    def add_col(self, co=[])
    def download_process(self, xxxxxx=None)

longer answer: python's not C++, and there's no automatic this/self
variable.  instead, the instance is passed as the first argument to the
method.

also see the tutorial, and FAQ entry 4.21 and 6.7:

    http://www.python.org/doc/FAQ.html#4.21
    "what is self?"

    http://www.python.org/doc/FAQ.html#6.7
    "Why must 'self' be declared and used explicitly in
    method definitions and calls?"
