After creating an instance of the usrp object use the object, 
not the class.   You want to invoke a method of the object.

    address@hidden tmp]$ python
    Python 2.4.1 (#1, Sep 13 2005, 00:39:20)
    [GCC 4.0.2 20050901 (prerelease) (SUSE Linux)] on linux2
    Type "help", "copyright", "credits" or "license" for more information.
    >>> from gnuradio import usrp
    >>> u = usrp.source_c(0, 64)
    >>> v = u.read_aux_adc(0, 0)
    >>> print v
    224

You might want to spend a bit of time with the python tutorial at
http://www.python.org/doc 

I prefer the pdf formatted version available here:
