Question

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

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

The output should be:

AMIT - B
NAGMA - C
DAVID - A 

Answer 1

def showGrades(S): 
      for n, marks in S.items(): 
          perc=sum(marks)/3 
          if perc>=90: 
             print(n + ":" + "A") 
          elif perc>=60: 
             print(n + ":" + "B")
          else: 
             print(n + ":" + "C")
