Perhaps you did not know that you can inheret directly from dict, which 
is the same as {}. For instance:

class Dict({}):
   pass

Is the same as

class Dict(dict):
   pass

Now Dict can do everything that dict ({}) can do, but you can also 
specialize it:

py> class Dict(dict):
...   def __str__(self):
...     return "I am %s long. But you should read the tutorial!" % len(self)
...
py> d = Dict()
py> d['a'] = 1
py> d['b'] = 2
py>
py> d['a']
1
py> d['b']
2
py> print d
I am 2 long. But you should read the tutorial!
