import random

#main takes no parameters.
#It introduces the rules of the game once, then runs an while loop as long as the user wants to continue playing the game.
#The while loop is where the game is played. A new random number is generated each iteration.
#The for loop gives the player eight chances to guess the random number.
#Each time the user guesses a number, two functions are called within the loop: one to validate the number and the other to compare it to the real answer.
#If the user guesses the number correctly, or fails to guess the number after eight guesses, the game is over and the for loop is exited.
