In python, write a program that reads a list of scores and then assigns grades
Have your program:
Use 100 for the best score
Begin the program and each function with a descriptive comment.
Define main( ) to call the two functions described below.
Define a function to prompt the user to enter valid scores until they enter a sentinel value -999. Have this function both create and return a list of these scores. Do not store -999 in the list!
Have main( ) then pass this the list to a second function which traverses the list of scores printing them along with their appropriate grade.
Run your program with a score within each of the possible grade ranges. See the sample output below.
Use local variables, rather than global.
Use structured code (e.g., no unstructured exits from loops).
Sample output:
94 is an A
83 is a B
72 is a C
61 is a D
59 is an F
