Some I

问题 I'm using Google Sheets's Script Editor to operate between the values of a table/array. I've got a table that looks like this: | UserA | UserB | UserC | Movie1 | 2 | 8 | 6 | Movie2 | 4 | 6 | 0 | Movie3 | 5 | 2 | 3 | Movie4 | 2 | 7 | 2 | I need to sum every user's rating with the first user's rating, obtaining another array with the results of each sum. In this case, the result should be: | UserA+A | UserB+A | UserC+A | Movie1 | 4 | 10 | 8 | Movie2 | 8 | 10 | 4 | Movie3 | 10 | 7 | 8 | Movie4 |

If $array contains your data $result = array( array_combine($array[0], $array[1]), array_combine($array

问题 Having a 4-D numpy.ndarray, e.g. myarr = np.random.rand(10,4,3,2) dims={'time':1:10,'sub':1:4,'cond':['A','B','C'],'measure':['meas1','meas2']} But with possible higher dimensions. How can I create a pandas.dataframe with multiindex, just passing the dimensions as indexes, without further manual adjustments (reshaping the ndarray into 2D shape)? I can't wrap my head around the reshaping, not even really in 3 dimensions quite yet, so I'm searching for an 'automatic' method if possible. What
