This is something that I have to do every once in a while and can never remember the method. To save myself some time, I've written this here in hope that I can remember it next time.
01.student_tuples = [02. ('john', 'A', 15),03. ('jane', 'B', 12),04. ('dave', 'B', 10),05.]06. 07.# sort by age08.sorted(student_tuples, key = lambda student: student[2])09. 10.[('dave', 'B', 10), ('jane', 'B', 12), ('john', 'A', 15)]This great example is straight from the Python wiki page.
