"""Guess the Number - Mini Project 2:
    This is a simple program of Guess the Number. The computer randomly
    chooses a number between 0 and 100 (or 0 and 1000) and the user is tasked
    to guess what the number is.

    The number of guesses is defined by the 'difficulty' of the range to guess.
