Write a user defined function in Python named showGrades(S) which takes the dictionary S as an argument. The dictionary, S contains Name:[Eng,Math,Science] as key:value pairs. The function displays the corresponding grade obtained by the students according to the following grading rules :

Average of Eng,Math,Science	Grade
>=90	A
<90 but >=60	B
<60	C

For example : Consider the following dictionary

python

S = {"AMIT":[92,86,64], "NAGMA":[65,42,43], "DAVID":[92,90,88]}

        elif sum(V)/3 >= 60:
            Grade = "B"
        else:
