This is cython-specific syntax indicating that the parameter X is a one-dimensional memory view (an array) whose elements are dtype_t. The information you saw about object copying has to do with standard python statements like "a_copy = a_original[:]", not examples like this one. -- https://mail.python.org/mailman/listinfo/python-list
