Re: [Numpy-discussion] PyArray_FromAny does not accept a generator?

It's difficult to do all the magical interpretation that PyArray_FromAny() does with a iterator of unknown length. In Python, we have fromiter() which will consume an iterator to make (only) a rank-1 array and thus sidestep a big chunk of the magical interpretation. I have previously created a wrapper for python around boost::ublas vector. Basically it does (in pseudocode): vector_from_object(obj): if (obj is a vector): return a copy elif (obj has __len__): return vector_from_sequence elif (obj has __iter__): return vector_from_iter vector_from_iter(iter): copy_iter_to_new_temp_container (in this case, we use std::vector with push_back) return new vector from temp container ___ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
