Project description

murmurhash is a fast hash function ::
>>> import featurehash
    >>> featurehash.hash("abc")  #return the hashcode of the string "abc"
    >>> featurehash.transform_feature("abc")   #return the code and the sign of hashcode;the code is equal to "hashcode mod 8388608"
            (2255878, -1.0)
    >>> featurehash.transform_features(["abc","edf","efd","123","efd"]) #pass a sequence to the function,return the sorted unique feature code.
            [123, 2255878, 3759815, 8023168]
    >>> featurehash.transform_features(["abc","edf","efd","123","efd"],8388607) #pass a sequence and upper_bound;upper_bound default 8388608(2^23)
    [123, 2256030, 3760023, 8023392]
    >>> featurehash.transform_features(["abc","edf","efd","123","efd"],8388607,1) #pass a sequence , upper_bound and seed; seed default 0;the same application use the same seed value.
    [123, 661164, 3231264, 8317657]
