Difference between unindexable and unsubscriptable

What is the difference between "object is unindexable" and "object is 
unsubscriptable"?

I would like to test if an object can accept:   obj[0]

 >>> from sets import Set
 >>> Set([1,2])[0]
TypeError: unindexable object

 >>> 3[0]
TypeError: unsubscriptable object

It seems like each of these errors can be replaced with a single type error.
