Python错误:“IndexError:字符串索引超出范围" [英] Python error: "IndexError: string index out of range"

问题描述

我目前正在从一本名为绝对初学者的 Python(第三版)"的书中学习 Python.书中有一个练习概述了刽子手游戏的代码.我跟着这个代码但是我一直在程序中间返回一个错误.

I'm currently learning python from a book called 'Python for the absolute beginner (third edition)'. There is an exercise in the book which outlines code for a hangman game. I followed along with this code however I keep getting back an error in the middle of the program.

这是导致问题的代码:

if guess in word:
    print("\nYes!", guess, "is in the word!")

    # Create a new variable (so_far) to contain the guess
    new = ""
    i = 0
    for i in range(len(word)):
        if guess == word[i]:
            new += guess
        else:
            new += so_far[i]
        so_far = new

这也是它返回的错误:

new += so_far[i]
IndexError: string index out of range

有人能帮我解决哪里出了问题以及我能做些什么来修复它吗?

Could someone help me out with what is going wrong and what I can do to fix it?

我像这样初始化了 so_far 变量:

edit: I initialised the so_far variable like so:

so_far = "-" * len(word)

推荐答案

看起来您将 so_far = new 缩进太多了.试试这个:

It looks like you indented so_far = new too much. Try this:

if guess in word:
    print("\nYes!", guess, "is in the word!")

    # Create a new variable (so_far) to contain the guess
    new = ""
    i = 0
    for i in range(len(word)):
        if guess == word[i]:
            new += guess
        else:
            new += so_far[i]
    so_far = new # unindented this
