Astrodata is an affiliated package that contains a collection of classes and functions to access online Astronomical data. Each web service has its own sub-package. For example, to interface with the SIMBAD website, use the simbad sub-package:
>>> from astroquery import simbad
>>> theta1c = simbad.QueryId('tet01 Ori C').execute()
>>> theta1c.table.pprint()
