List index method for complex list item types?

[techiepundit at futurepundit.com]

Mike,

I'm trying to figure out dictionaries using the documentation. Clicking
on "dictionary type" takes me to "2.3.8 Mapping Types -- classdict". Is
that the documentation for the dictionary type? If so, I do not see an
"append" or "add" or "insert" method defined in the list of methods on
that page.

Here's what they list:

Operation Result Notes
len(a) the number of items in a
a[k] the item of a with key k (1)
a[k] = v set a[k] to v
del a[k] remove a[k] from a (1)
a.clear() remove all items from a
a.copy() a (shallow) copy of a
a.has_key(k) True if a has a key k, else False
k in a Equivalent to a.has_key(k) (2)
k not in a Equivalent to not a.has_key(k) (2)
a.items() a copy of a's list of (key, value) pairs (3)
a.keys() a copy of a's list of keys (3)
a.update([b]) updates (and overwrites) key/value pairs from b (9)
a.fromkeys(seq[, value]) Creates a new dictionary with keys from seq
and values set to value (7)
a.values() a copy of a's list of values (3)
a.get(k[, x]) a[k] if k in a, else x (4)
a.setdefault(k[, x]) a[k] if k in a, else x (also setting it) (5)
a.pop(k[, x]) a[k] if k in a, else x (and remove k) (8)
a.popitem() remove and return an arbitrary (key, value) pair (6)
a.iteritems() return an iterator over (key, value) pairs (2), (3)
a.iterkeys() return an iterator over the mapping's keys (2), (3)
a.itervalues() return an iterator over the mapping's values (
