Как прочитать текстовый файл и преобразовать числа в целые числа, чтобы получить общее значение

Question

Я пытаюсь прочитать GolferScores из txt-файла, который был создан и считан с накопления итогового значения, а затем определить среднее значение. Я хочу. Я пытался собрать все это в своей функции GolfRead

Я пытался создавать объекты while и readline (), но мне чего-то не хватает.

def Main():
    import time  #Imports time module
    time.sleep(2)#delay of 2 seconds

    Welcome() #Call Welcome Function

    #Constants for the menu choices


    AverageGolfScore = 0 #Initialize Variable

    #Display the menu
    GolfMenu()

def Welcome():
    print('This is a menu-driven program\n' +
          'that allows you to write, append and read\n' +
          'data to and from a file.\nProgram developed by Robert 
           Hernandez')
    print('')#Prints blank space

#Append Choice Menu Function
def GolfAppend():
    #Warn User
    confirm = input('This will add data to an existing data file.\nIf you 
                    do not wish to continue' +' with this action\n' + 'hit N or n to return to 
                    menu.\n' +
                    'Otherwise press Enter key to continue: ')

#While Validation Loop
while confirm != 'N' and confirm != 'n' and confirm != '':
    print('Invalid Input')
    confirm = input('Press N or n to return to menu.\nOtherwise press Enter key to continue: ')

#Warn User if statement
if confirm == 'N' or confirm == 'n':
    GolfMenu()     
elif confirm == '':

    #Get the number of golfers records to create.
    NumGolfers = int(input('How many golfers records ' +
                           'do you want to create? '))

    #Validate # of golfers input
    NumGolfers = ValidNumGolfers(NumGolfers)

    #Open a file for writing.
    GolfFile = open('golfers.txt', 'a')



    #Get each golfers data and write it to
    #to the file
    for count in range(1, NumGolfers + 1):

        #Get the data for a golfer
        print('Enter the data for golfer #' , count, sep='')

        GolfFile.write(GolferName.capitalize() + '\n')
        GolfFile.write(str(GolferScore) + '\n')

        #Display a blank line.

    print('Golfers records written to Golfers.txt. ')

    #Returns to menu
    GolfMenu()

#Read Choice Menu Function

        #which is the name field of first
