numpy array using python's long type
Python's long integer type is not a native numpy type, so you will have touse the object data type. The elements of an numpy array with object type can be any python objects.
For example,
In [1]: x = np.array([1L, 2L, 3L], dtype=object)In [2]: xOut[2]: array([1L, 2L, 3L], dtype=object)In [3]: x[0]Out[3]: 1LIn [4]: type(x[0])Out[4]: longWhether or not this is useful for you depends on what you want to do with the array of longs.
