Python 错误 : "IndexError: string index out of range"

Question

我目前正在通过一本名为“Python for the absolute beginner (third edition)”的书学习 python。书中有一个练习概述了刽子手游戏的代码。我遵循了这段代码，但是我一直在程序中间返回错误。

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

有人可以帮我解决问题吗？我可以做些什么来解决这个问题？

编辑:我像这样初始化了 so_far 变量:

so_far = "-" * len(word)

看起来你 so_far = new 缩进太多了。试试这个:

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
