类型错误：整数类型的参数不可迭代？

Question

我正在尝试用Python 2.7写一个猜单词游戏（也叫“吊死鬼”），但是在代码中有一行出现了类型错误，那一行是：

print char.

抱歉，我忘了加上其余的代码。下面是完整的代码。这个单词是从一个字典文件中获取的。

import random
import string

WORDLIST_FILENAME = "words.txt"

def load_words():

    print "Loading word list from file..."
    # inFile: file
    inFile = open(WORDLIST_FILENAME, 'r', 0)
    # line: string
    line = inFile.readline()
    # wordlist: list of strings
    wordlist = string.split(line)
    print "  ", len(wordlist), "words loaded."
    return wordlist

def choose_word(wordlist):
    return random.choice(wordlist)

wordlist = load_words()
print "Welcome to Hangman where your wits will be tested!"
name = raw_input("Input your name: ")
print ("Alright, " + name + ", allow me to put you in your place.")
word = random.choice(wordlist)
print ("My word has ")
print len(word)
print ("letters in it.")

guesses = 10
failed = 0
for char in word:
        if char in guesses: 
            print char,
        else:
            print "_",
            failed += 1
            if failed == 0:
                print "You've Won. Good job!"
                break
            # 
            guess = raw_input("Alright," + name + ", hit me with your best guess.")
            guesses += guess
            if guess not in word:
                guesses -= 1
                print ("Wrong! I'm doubting your intelligence here," + name)
                print ("Now, there's only " + guesses + " guesses left until the game ends.")
                if guesses == 0:
                    print ("I win! I win! I hanged " + name + "!!!")

Answer 1

你尝试：

if char in guesses: 

不过，guesses 只是剩余猜测次数的 计数，是一个整数，所以你不能对它进行循环操作。也许你应该把之前的猜测也存起来，然后使用这些：

guess_list = []
...
if char in guess_list:
...
guess_list.append(guess)

出于同样的原因，如果你走到了这一步，

guesses += guess

会失败 - guess 是一个字符串，而 guesses 是一个整数，这两者是不能直接相加的。
