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!
