>>> dict={}
>>> dict[1]="Foo"
>>> print dict[1]
Foo

This dictionary method is also useful:

>>> print {}.get.__doc__
D.get(k[,d]) -> D[k] if D.has_key(k), else d.  d defaults to None.

i.e. to have a default value of 42 for the key 2 which is used
when an entry for 2 is missing: 

>>> print dict.get(2, 42)
42
