Unpacking numpy array gives list rather numpy array. >>> import numpy as np >>> a = np.array([1,2,3,4]) >>> x, *y, z = a >>> type(a) <class 'numpy.ndarray'> >>> type(y) <class 'list'>> >> type(x) <class 'numpy.int32'> |

It doesn't matter what you're unpacking, *y will collect the unpacked elements into a list. |

Yes, you are unpacking into a list, that's what the * syntax does in this context. Since the rhs can be a mix of types, there's really no other reasonable meaning for the syntax. (The same is true for tuples, by the way). |
