How to Select Elements in List in Mathematica Examples
There are multiple ways through which you can select the elements from list. And it can be pretty much easier if you know how to select the elements with simple functions instead of going through all the elements. So here are some of the examples that you can check out.
Pick[list[[All, 1]], UnitStep[list[[All, 2]] - 8], 1]
and
list = {{1, 11}, {2, 7}, {4, 2}, {7, 9}, {-2, 3}, {-1, 10}};
Select[list, #[[2]] > 8 &][[All, 1]]
