keep_playing的绞刑者游戏麻烦
keep_playing的绞刑者游戏麻烦
提问于 2013-07-01 22:42:48
因此，我是python的新手，通过一个教程，在我的新pi上用python2.7编写了一个绞刑者游戏。好吧，不管怎么说，我喜欢代码和所有的东西，它运行得很好，但是我想添加一些东西，让它问，“如果你想继续玩”，我做了很多研究，在一些聊天室里谈到了它，并提出/找到了这个脚本来退出：
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")但是我得到了这个错误：
Traceback (most recent call last):
File "/home/pi/Desktop/Scripts/scrappy/ls/ls/hangman3.py", line 40, in <module>
while keep_playing == False:
NameError: name 'keep_playing' is not defined当它与此脚本一起运行时
import random
import urllib
print 'time to play hangman'
animals = urllib.urlopen('http://davidbau.com/data/animals').read().split()
secret = random.choice(animals)
guesses = 'aeiou'
turns = 5
while turns > 0:
missed = 0
for letter in secret:
if letter in guesses:
print letter,
else:
print '_',
missed += 1
print
if missed == 0:
print 'You win!'
break
guess = raw_input('guess a letter: ')
guesses += guess
if guess not in secret:
turns -= 1
print 'Nope.'
print turns, 'more turns'
if turns < 5: print ' O '
if turns < 4: print ' \_|_/ '
if turns < 3: print ' | '
if turns < 2: print ' / \ '
if turns < 1: print ' d b '
if turns == 0:
print 'The answer is', secret
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")有人可以帮助我吗？*编辑*有人可以使用提示关闭这个踏步，只要我已经解决了我的问题这是最终的代码
import random

我对python不感兴趣，但我可以看出您确实在尝试将一个空的/未定义的变量"keep_playing“与false进行比较。据我所知，不能将一个变量与某个东西进行比较，如果在比较之前没有声明变量，则不能确定这在Python中是否不同。
如果沿着其他变量写下这一行，会发生什么：
keep_playing = False所以你会得到：
animals = urllib.urlopen('http://davidbau.com/data/animals').read().split()
secret = random.choice(animals)
guesses = 'aeiou'
turns = 5
keep_playing = FalseStack Overflow用户

keep_playing = False这应该就行了
