Write a python program that asks the user to enter a student's name and 6 numeric tests scores (out of 100 for each test). The name will be a global variable. Create functions to calculate a letter grade for the student and calculate the average of the test scores for the student. The program should display a letter grade for each score, and the average test score, along with the student's name. Assume 6 students in the class.

Functions in the program:

the function should accept 6 test scores as arguments and return the average of the scores per student

the function should accept a test score average as an argument and return a letter grade for the score based on the following grading scale:

90-100 A

80-89 B

70-79 C

60-69 D

Below 60 F

Data for the program:

Jill Tree 70 66 87 82 75 73

Francis Ricks 90 93 87 84 91 93

Sally Smith 99 97 92 90 88 89

John Jones 72 86 59 69 72 78

Tommy Rimes 87 83 86 90 80 88

Erin Ames 66 69 72 61 73 71
