Simple Method to calculate average and grade

[ajitnayak1987]

I have tried like this . But i wanted to return grade for both student_average

import numpy
myList=[[85,80,98,94],[87,9,75,60]]
New_grade=[]

def print_student_average(myList):
    students_avg = numpy.mean(myList, axis=1)
    for avg in students_avg:
        if(avg>=90):
            New_grade='A'
        elif avg>=80 and avg<=90:
            New_grade='B'
        elif avg>=70 and avg<=80:
            New_grade='C'
        elif avg>=60 and avg<=70:
            New_grade='D'
        else:
            New_grade='F'
            
        print(avg)
    #return students_avg
    return New_grade

Average=print_student_average(myList)
print(Average)
