lessons_learned = '''====================
For positive values:
    int(n), str(int(n)), float(n), str(float(n)) all work correctly.
For negative values:
    Only int(n) and float(n) work correctly.
Recommendation:
    Always pass an int or float as the second value to highscores.is_high_score()
Added a try / except block to reject nonnumeric scores'''
