'''
Write a function
sortby_result(students: list)
which takes a list of tuples as its parameter. A single tuple represents the student's exam results. The first tuple is the student's name (string) and the next three are the student's scores (integers) in the three different exams of the course. Since only the best exam result for each student is taken into account, the exam list should be arranged in ascending order so that only the best of the three exam results for each student is taken into account as a ranking criterion.
Note! You can either use a lambda statement or write your own value function. This does not affect the marking.
