Please note that the 3 apostrophes beside the first student name Jade and the last student score of 100 are required for the test case to pass.

Write a python function max_scores(grades) that takes in a gradebook of students and returns a stripped multiline string where each line is in the form student_name: max_score. A gradebook is a multiline string where each line contains the students name followed by their scores, separated by commas.

Hint #1: You may want to use .split() and .splitlines(). Hint #2: Remember that the scores are strings you need to convert them to integers first. Hint #3: Make sure to use the .strip() method at the end to get rid of trailing spaces.

Test

grades = '''Jade,50,64,82,14

Brenda,90,67,73,80

Chris,75,75,75,75

John,100,85,90,99'''

assert(max_scores(grades) == '''Jade: 82

Brenda: 90

Chris: 75

John: 100''')
