我正在使用python 2.7.1制作一个刽子手游戏。我试图让用户在游戏结束前选择是否重播。我试图使用变量keep_playing，但它不起作用。
另外，在guesses=word_len * ['_']中，我想在下划线之间留一个空格，因为如果它们粘在一起，我就看不到剩下多少个字母了。这是我的刽子手代码：
from random import *
import os
keep_playing = True
def print_game_rules(max_incorrect,word_len):
print"you have only 7 chances to guess the right answer"
return
def get_letter():
print
letter = raw_input("Guess a letter in the mystery word:")
letter.strip()
letter.lower()
print
os.system('cls')
return letter
def display_figure(hangman):
graphics = [

print "The word was",word
keep_playing = False
if letters_correct == word_len:
print "You guessed all the letters in the word!"
print "The word was",word
keep_playing = False
while keep_playing == False:
user = raw_input("\n\tShall we play another game? [y|n] ")
again = "yes".startswith(user.strip().lower())
if again:
keep_playing = True
if not again:
break
raw_input ("\n\n\nPress enter to exit")
答案 0 :(得分：3)
print ''.join(guesses)可以转换为print ' '.join(guesses)，在字母之间留出空格
你需要在keep_playing = False之前做while keep_playing == False:并且主游戏循环应该在一个从这个循环中调用的函数if keep_playing == True:

以下将做你想做的事。
from random import *

keep_playing = True

print"you have only 7 chances to guess the right answer"

letter.lower()
