Answer 1

SINKREAN VAEGAN GATES KLINßMANN ,

as already mentioned by Calviղ , we need an integer number to access the numpy rows or columns of an array.
(please see your code sample (in the attached file) that is modified slightly. i also renamed the input variable *column_name* to *ind*)

> the code: column = np.array(data[ind]) does access a *row* of the current array.

> if we need to get a column of the array, we can do it this like: column = data[:, ind]

Answer 2

In order to access a specific column in a NumPy array, you need to use the index of the column rather than its name.
