I have the following list data = { {11, {121, 122}}, {21, {221, 222}}, {31, {321, 322}} }; >From each sublist, I want to extract the first element and the second element of the second sub-sub-list that is: wanted_result={ {11, 122}, {21, 222}, {31, 322} } I tried data[[All, {1, {2,1}}]] but it gives me error. What is the right selector ?
