There's no dict.append or dict.add because a dict doesn't require
them. You insert keys via the normal indexing interface:
somedict[somekey] = somevalue.
Depending on which direction your mapping is, you may be interested in
the setdefault method.
The dict constructor is described in section 2.1, built in functions
(even though it's not a function anymore).
The other dict methods are described in section 3.8, mapping types.
