    Key insensitive dictionary in Python

    written by Sergio Fernández at 19h34

    How nice looks a key case-insensitive dictionary written in Python:

    class KeyInsensitiveDict:
    

    def init(self, d={}):
        self.dict[“d”] = {}
        for k, v in d.items(): self[k] = v

    def getattr(self, attr):
        return getattr(self.dict[“d”], attr)

    def setattr(self, attr, value):
        setattr(self.dict[“d”], attr, value)

    def setitem(self, key, value):
        if (hasattr(key, “lower”)):
            key = key.lower()
        self.dict[“d”][key] = value

    def getitem(self, key):
        if (hasattr(key, “lower”)):
            key = key.lower()
        return self.dict[“d”][key]

    Actually it’s just a simple usage of the decorator pattern. And I wrote this code because we need it for the Python SPARQL Wrapper.
