Since this operation is not permitted, NumPy raises a ValueError, similar to the matrix multiplication operator.Instead, you need to take the transpose of one of the arguments:Python In [12]: arr_row.T Out[12]: array([[1], [2], [3]]) In [13]: sc_prod = arr_row @ arr_row....
But what if we prefer to use the elements of one column as the keys and the elements at other columns as the values? It is possible by simply making the required column as the index of the DataFrame and taking its transpose using.T()function. ...
