Ошибка индекса: индекс списка вне ранжирования (python 3.2)

Question

Я и мои друзья работаем над проектом в школе, и мы понимаем, почему возникает ошибка, но мы не можем видеть, где мы сделали эту ошибку. Мы уверены, что мы посчитали это правильно, и мы знаем, что в индексе он начинается с 0, но это все еще неправильно. Наша задача - создать игру, которая перемещает игроков по сетке 7x7, но мы должны вставить некоторые игровые сообщения из-за пределов кода, который мы храним, в тот же файл. PS нам разрешено обращаться за помощью. Вот код Пожалуйста, помогите!:

import random


counter1 = 0

 counter2 = 0


print("***********************************BOARD GAME**********************************")

 print(" ")

 print("***********************************GAME RULES**********************************")

 print(" ")

 print("----------------------------Game is for 2 players only-------------------------")

    Actually the problem is getting the file contents from Game Messages.txt.
    So, first the whole file contents need to be converted into list.

**Please follow this procedure in your program first**
    with open('Game Messages.txt', 'r') as infile:

        data = infile.read()  # Read the contents of the file into memory.

    # Return a list of the lines, breaking at line boundaries.
    my_list = data.splitlines()
    print (my_list)  #It will give whole file contents as an array
    #Eg : ['game message1', 'game message2', 'game message3', 'game message4', 'game message5']
    print (my_list[3])  # It will display game message 4
    So in your program
    instead of
    if dice1 == dice2:

     counter2 = counter2 - dicetotal

     print(newfile.readlines()[7])     #This is one of the lines that is coming up as an error

    else:

     counter2 = counter2 + dicetotal
    it will be
    if dice1 == dice2:

     counter2 = counter2 - dicetotal

     print(my_list[3])     #You need to give exact line number, in case 4th means it #will be my_list[3] as array index starts with 0 only
    else:

     counter2 = counter2 + dicetotal

    Hope that helps
