Hi All--
I have a 2D array (2000, 4); an example is given abelow. On the 1st column I have 15 variables, on the 2nd 4 variables. Ignore column 3 for now. I want a code that generate 4 arrays for each variable on the 1st column; each array contains all the values from column 4. Then I want to find the average of each array. For example; pick the 1st variable in column 1 which is 1; then pick the 1st variable on the 2nd column which is 5. Now I want an array that contains all the values on the 4th column that match variable 1 on the 1st and variable 5 on the 2nd column. I need to get the average of each array. A b c d 1 5 3 4 1 3 2 7 2 5 7 5 3 2 8 5 2 3 2 3 Thanks in advance—EKE _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
