In Python, what does it mean if an object is subscriptable or not?

Question

Which types of objects fall into the domain of "subscriptable"?

Answer 1

It basically means that the object implements the __getitem__() method. In other words, it describes objects that are "containers", meaning they contain other objects. This includes lists, tuples, and dictionaries.

Answer 2

I think you mean "subscriptable", in which case mipadi's definition is spot-on!

Answer 3

A scriptable object is an object that records the operations done to it and it can store them as a "script" which can be replayed.

For example, see: Application Scripting Framework

Now, if Alistair didn't know what he asked and really meant "subscriptable" objects (as edited by others), then (as mipadi also answered) this is the correct one:

A subscriptable object is any object that implements the __getitem__ special method (think lists, dictionaries).

Answer 4

Off the top of my head, the following are the only built-ins that are subscriptable:

string:  "foobar"[3] == "b"
tuple:   (1,2,3,4)[3] == 4
list:    [1,2,3,4][3] == 4
dict:    {"a":1, "b":2, "c":3}["c"] == 3

But mipadi's answer is correct; any class that implements __getitem__ is subscriptable
