Normalize Grades

Given a list of tuples featuring names and grades on a test, write a function normalize_grades to normalize the values of the grades to a linear scale between 0 and 1.

Example:

Input:

grades = [
    ('Jason', 94),
    ('Tessa', 80),
    ('Carla', 38),
    ('Matt', 43),
    ('Jessica', 100)
]

Output:

def normalize_grades(grades) - > [
    ('Jason', 0.9),
    ('Tessa', 0.68),
    ('Carla', 0.0),
    ('Matt', 0.08),
    ('Jessica', 1.0)
]
