所以,我正在为一个学校项目制作这个刽子手游戏,并且遇到了一个问题,我不能为我的生活弄清楚甚至为什么它会发生。
word_list = ["APPLE", "PEAR", "BANNANA"]
word = word_list [random.randint(0,2)]
hidden_word = ["_ " * len(word)]
print (word)
这段代码是一个列表,然后是一个字符串变量:
word = word_list [random.randint(0,2)]
然后,我创建了一个隐藏单词的新列表,其中包含' _'通过获取长度来隐藏:
hidden_word = ["_ " * len(word)]
然后我打印出来(用于开发)
print (word)
查看有问题的代码。
def click_1 (key):
if str(key) in word:
key_1 = word.index(key)
print (key_1)
hidden_word[key_1] = key
print (hidden_word)
else:
print ("Nope")
return letter
r = c = 0
for letter in string.ascii_uppercase:
Button(letter_frame, text=letter, command=functools.partial(click_1, letter)).grid(row=r, column=c, sticky=W)
c += 1
if c > 12:
c = 0
r += 1
这会让按钮出现,当我点击带有字母的按钮时,会检查单词中是否有,然后(此时)打印:
BANNANA
>>> 0
['B']
如果这个词是bannana。问题是我按A:
1
出现,如果我按其他内容,则会出现此错误:
Exception in Tkinter callback
Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/idlelib/run.py", line 121, in main

During handling of the above exception, another exception occurred:

return self.func(*args)
File "/Users/alexeacott/Desktop/Hangman.py", line 24, in click_1
hidden_word[key_1] = key
IndexError: list assignment index out of range
最后一行是最交叉的,因为很明显,N超出了范围。我的问题是,为什么会发生这种情况,我该怎么做才能解决。
节日快乐!
答案 0 :(得分:3)
以下行创建一个包含单个元素的列表(elemnt是一个字长已长的字符串“_ _ _ ...”字符串):
hidden_word = ["_ " * len(word)]
访问元素(索引> 0)会导致IndexError
,因为列表中只有一个元素。
您可能想要创建多个元素的列表:
hidden_word = ["_ "] * len(word)
>>> ["_ " * 3]
['_ _ _ ']
>>> ["_ "] * 3
['_ ', '_ ', '_ ']
