Trying to check what properties methods are available in APIs

[breako]

Hi,
Sorry simple question.  New to Python from a Java background.

In Java I could just check an objects API to see what I could do with in 
it. In Google's spreadsheet python library there's lots o useful objects 
but how or where do I check to see what I can do with say a GetCellsFeed?  
What APIs can I call on it?  Similarly for every entry in a Cells feed?

Thanks.
