Add cells from one column and add them to another new column

How to add pairs of elements of a column, and add them to a new column, until all the elements of the first column in Jupyter Notebook, attached the annexed image, where my origin column is m, and it is necessary to add pairs of cells such as color marked and add to the column, how? Until the end of the entire column

thank you so much

Depending on the type of table/list/dataframe of the data you could just iterate i from 1 to len(m) and push to the new column at index i the sum of m[i] and m[i-1].

Ok, I’ll try it this way,
Thank you very much
