有什么原因我不能让.upper（）工作吗？一直在给一个叫做AttributeE的东西

Question

import random

def wordlist():
    wordlistfile=open("dictionary.txt","r")
    word_list=[]
    for line in wordlistfile:
        strip_line=line.strip("\n").lower()
        word_list.append(strip_line)
    return (word_list)

#I want to change the .lower() here to .upper() but it keeps breaking as soon as
#change it and have to keep changing it back. This function opens the word list
#file and converts into a comma seperated list.

def randomword(words_list):
    word = random.randint(0, len(words_list)-1)
    return words_list[word]

#This function picks a random integer in the range of the word list and uses that
#integer to call an indexed word

    print(hangmanpictures[len(wrongletters)])

    for letter in blanks:
        print(letter, end=" ")
    print("\nWrong letters: ", end=" ")
    print()
    for letter in wrongletters:
        print(letter, end=" ")

#function that runs the game

        else:
            return guess

#function that checks whether or not if a guess is a valid guess or not
#I was trying to change the guess into .upper() as well to match the character
#from the word that is randomly chosen from above, but something kept breaking
#and I had to change it back

    choice = input("Do you want to play again? (Y or N): ").upper()
    return choice
#wanna play again?

在解决了前面的问题之后，我尝试使用.upper（）将所有单词和用户输入大写，但是pythonshell一直给我一个名为AttributeError about for.upper之类的东西。你知道吗

我试过的是在def wordlist（）函数中，我把strip\u行=线条.strip（“\n”）.upper（）并在def guesses（guessed）函数中输入guess=猜猜看。上（）它不断地破裂。不过，当我把这些改回使用.lower（）时，效果非常好。但为了美观起见，我希望它是大写字母，因为我认为大写字母比小写字母更好看。你知道吗

对于那些关心这个问题的人来说，我之前在这段代码中遇到的错误是，我没有在def wordlist（）函数中放入.lower（）。你知道吗

Answer 1

循环中有一个bug填补了hangingman的空白：

            blanks = blanks[:1] + random_word[i] + blanks[i+1:]

除了字符串的第一个字符外，您正在切掉所有字符。应该是的

            blanks = blanks[:i] + random_word[i] + blanks[i+1:]

注i代替1。你知道吗

为了在Python2.7和python3中运行这个程序，我做了一些小的编辑，现在它可以为我工作了。以上是唯一的逻辑变化。你知道吗

为了您将来的使用，我所做的只是运行程序，查看输出在何处出现异常，然后卡在print语句中跟踪值。如果你有病人，问问哪里疼。你知道吗

for i in range(len(random_word)):
    if random_word[i] in rightletters:
        blanks = blanks[:i] + random_word[i] + blanks[i+1:]
        print "DEBUG", i, blanks
