Python初学者在这里:TypeError: 'str'对象不支持项分配

I just started programming with python a couple days ago with no prior experience in programming.

几天前，我刚开始使用python编程，以前没有编程经验。

I've been following tutorials online and decided to challenge myself by making a hangman-esque game. I'm trying to make it so that a guess replaces the position an alphabet in the hidden word but python is returning this error. Right now the word is called name and the hidden_name are just #'s in the same length.

我一直在关注在线教程，并决定通过制作一个类似刽子手的游戏来挑战自己。我试着让猜测取代了隐藏单词中的字母表但是python返回了这个错误。现在，这个词叫做name，而hidden_name的长度是一样的。

    name = input ("what is your name ::")
    hidden_name = ("#" * len(name))
    print (hidden_name)

    guess = input ("Guess a letter ::")
    def guess_update(guess, name, hidden_name):
        right = guess in name 
        i = 0
        for c in name:
            if c == guess:
                hidden_name[i] = c
            i += 1
    if guess in name:
        guess_update(guess, name, hidden_name)
        print ("Your progess is ::", hidden_name)

Thanks for helping this newbie out :)

谢谢你帮助这个新手。

2 个解决方案

#1

Strings in Python are immutable, so you cannot do this:

Python中的字符串是不可变的，所以不能这样做:

hidden_name[i] = c

One option which will achieve the desired effect for your game is:

一种可以达到你的游戏预期效果的选择是:

hidden_name = hidden_name[:i] + c + hidden_name[i+1:]

This works because you are creating a new string using concatenation, and re-assigning the result back to the variable, rather than attempting to edit the existing string.

这是因为您正在使用连接创建一个新的字符串，并将结果重新分配给变量，而不是尝试编辑现有的字符串。

#2

Strings in python are inmutable, so you cannot change its content. One solution would be to split the string, change the letter and stick it back together:

python中的字符串是不可修改的，所以不能更改其内容。一种解决办法是把绳子分开，改变字母，再把它粘在一起:

splitted = list(hidden_name)
splitted[i] = c
hidden_name = ''.join(splitted)
