def gradeAverage():
grades = []
i = 0
while i < 5:
a = int(input('enter score ' + str(i + 1) + ': '))
grades.append(a)
i = i+1
#print(grades)
average = sum(grades)/len(grades)
#print(average)
return average

if a < 60:
letter = 'F'
elif 59 < a < 63:

elif 62 < a < 67:
letter = 'D'
elif 66 < a < 70:

Explanation:
The programming language used is python.
Two functions were created, the first function gradeAverage() was used to calculate the average values of the scores.
The second function lettergrade(a) was used to get the letter grade i.e(A, A-, C, D, e.t.c.) and it takes its argument from the average.
The main block of code asks for how many students are there and prompts the user to input their names and scores for all the students.
It takes that data calculates the average and the letter grade and prints out the names of the students, their average and their letter grade.

Please find the detailed answer as follows:
Explanation:
Long-term average cell rate is also called as sustained cell rate(SCR). It can be defined as the maximum average cell rate in a log time period(T).
The relation among the SCR, Average cell rate and Peak cell rate is as follows:
Avg.cell rate ≤ SCR ≤ PCR
If the source producing fixed-length cells at constant rate, then the long-term average cell rate will be same as peak cell rate(PCR).
