Complete the getResults function. It takes in a $2$D list of integers data$\_$list and an empty list stat$\_$results as its parameters. The function will go through each sub$-$list in data$\_$list and get the average and the standard deviation and append it to the stat$\_$results list. stat$\_$results will be a $2$D list with each sub$-$list including two elements: average and standard deviation for the corresponding sub$-$list in data$\_$list.
