Statistics on class team grouping of (assistant may be required)

Ideas: very simple. First of all student's name and student number read it from the list of students to excel file dict dictionary, and the dictionary dict state students create, save for grouping students are in no state. Then read line by line grouping teams excel file, the students state dict dictionary set.
