Python3 画哈根曼游戏代码

Question

我有一段可以运行的Python 3的猜单词游戏代码，但我不知道怎么让用户在主函数里选择难度（简单（9个字母）、中等（7个字母）、困难（5个字母））。另外，有没有更简单的代码可以用来实现这个功能？

import random 
WORDLIST = ("phone", "laptop", "desktop", "sewer", "television", "never", "guess", "nice", "chair", "car");
WORD = random.choice(WORDLIST)
ACCEPTABLE = ("abcdefghijklmnopqrstuvwxyz")

guessed = []
state = 0
hasWon = 0
playedOnce = 0

def menu ():
    print("""
    1. Easy (9 misses)
    2. Medium (7 misses)
    3. Hard (5 misses)
    """)
    return int(input("What level do you want to play?:"))

def wantsToPlay():
    if (not playedOnce):
        return 1
    l = input("\nWould you like to play again? (y/n)")
    while (l != "y" and l != "Y" and l != "n" and l != "N"):
        l = input("\nWould you like to play again? (y/n)")
    if (l.lower() == "y"):
        return 1
    return 0

def takeNewLetter():
    global state, hasWon
    newPrint("So far, you have guessed the following letters...")
    for g in guessed:
        print(g, end=" ")
    letter = input("\n\nWhat letter would you like to guess next?\n")
    while (letter in guessed or letter not in ACCEPTABLE):
        if (len(letter) > 1):
            if (letter.lower() == WORD.lower()):
                 newPrint("You win!")
                 hasWon = 1
                 break
            else:
                newPrint("Boo... that was wrong... you're dead...")
                state = 7
                break
        else:
            if (letter not in ACCEPTABLE):
                letter = input("That character is unacceptable. You many only enter lower case letters.\n")
            else:
                letter = input("You have already guessed that letter, try another one...\n")
    guessed.append(letter)
    if (letter not in WORD):
        state += 1
    return

def drawWord():
    tempWord = ""
    for c in WORD:
        if (c in guessed):
            tempWord += c + " "
        else:
            tempWord += "_ "
    newPrint(tempWord)
    return

def drawStickman():
    if (state >= 7):
        print("   _______")
        print("|/      |")
        print("|      (_)")

你真正需要的是一个玩家可能犯错的次数。所以我写了一个 menu() 函数来返回这个值：

def menu():
    print("""
    1. Easy (9 misses)
    2. Medium (7 misses)
    3. Hard (5 misses)
    """)
    while True:
        level = input("What level do you want to play?:")
        if level in ('1', '2', '3'):
            return {'1': 9, '2': 7, '3': 5}[level]
        print('Wrong answer!')

现在你需要把这个菜单和它的结果放到你的主程序里。在 setup_game() 之后调用你的菜单函数，并把原本的常量 7 替换成它的结果。

def main():
    global guessed, hasWon, state, playedOnce, WORD, WORDLIST
    setup_game()
    allowed_misses = menu()
    ...
        while (hasGuessed() == 0 and state < allowed_misses)

你还应该从 hasGuessed() 函数中去掉状态检查，因为这个检查是多余的，而且使用了一个常量值。
