Question

class students:
      count=0
      def __init__(self, name):
          self.name = name
          self.scores = []
          students.count = students.count + 1

      def enterScore(self):         
           for i in range(4):
                m = int(input("Enter the marks of %s in %d subject: "%(self.name, i+1)))
               self.scores.append(m)    
        def average(self):
                avg=sum(self.scores)/len(self.scores)         
                 return avg      
        def highestScore(self):          
                return max(self.scores)  

      def display(self):        
                 print (self.name, "got ", self.scores)    
                 print("Average score is ",average(self))        
                 print("Highest Score among these courses is",higestScore(self))
       
 name = input("Enter the name of Student:")
 s = students(name)
 s.enterScore()
 s.average()
 s.highestScore()
 s.display()

So I need to print two things, first one is to compute the average score of these courses and second one is to print out the course name with the highest score among these courses. Moreover I need to import matplotlib.pyplot as plt to show the score figure. I barely could pull the code this far and it doesn't even print the first two things properly, let alone the figure. It shows NameError that 'average' isn't defined. Can someone please help me to bring this together? I'm totally lost!
