data set convert to matrix with tupel

I need to convert a part of my data to make it compatible with this solution: https://stackoverflow.com/a/64854873

The data is a pandas.core.frame.DataFrame with:

      result  data_1  data_2
1    1.523     4        1223
3    1.33     84        1534

Some index values might be removed, therefore 1, 3, ...

It should be a tuple with data values and the result. The type in the solution was scipy.sparse._coo.coo_matrix, like:

  (4, 1223) 1.523
  (84, 1534) 1.33

Just scipy.sparse.coo_matrix(df.values) seems to mix the data.

  (0, 0)    1.523
  (0, 1)    1.53
  (0, 24)   1.92
  : :
  (2, 151)  123.0
  (2, 142)  834.0

How can I generate a compatible matrix?
