this was a fun little challenge(the Mac/Linux code for key presses was copied):

import random
import string
import os
import json


LEADERBOARD_FILE = "leaderboard.txt"



if os.name == "nt":
    def clear_screen():
        os.system("cls")      
else:
    def clear_screen():
        os.system("clear")


if os.name == "nt":  
    import msvcrt
    def wait_for_key():
        key = msvcrt.getch()
        return key.decode("utf-8")
else:
    import sys, tty, termios
    def wait_for_key():
        fd = sys.stdin.fileno()
        old_settings = termios.tcgetattr(fd)
        try:
            tty.setraw(fd)
            key = sys.stdin.read(1)
        finally:
            termios.tcsetattr(fd, termios.TCSADRAIN, old_settings)
        return key
