帮我弄清楚 for 循环在这里做什么

# Hangman Game
#
# The classic game of Hangman.  The computer picks a random word
# and the player wrong to guess it, one letter at a time.  If the player
# can't guess the word in time, the little stick figure gets hanged.

# imports
import random

# constants
HANGMAN = (

else:
    print("\nYou guessed it!")

print("\nThe word was", word)

input("\n\nPress the enter key to exit.")

请帮忙，解释一下 for 循环的本质，用人类语言写下这里发生的事情：

 used.append(guess)

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

        # create a new so_far to include guess
        new = ""
        for i in range(len(word)):
            if guess == word[i]:
                new += guess
            else:
                new += so_far[i]              
        so_far = new
python

  1. Best Answer

    最初

    so_far = "-" * len(word)

    按代码，包含的字符数 '-'等于单词的长度或字母的数量。然后循环

    new = "" # create a new so_far to include guess / создается переменная "new" для 
                                              взаимодействия с "so_far"

    对于我在范围内（len（word））：

    if guess == word[i]:  / по буквам сравнивает, если буква в этом отгадываемом слове
    new += guess      /если есть в место символа '-'вставляем букву и сохраняем в "new"   
else:
    new += so_far[i]  / если нет, допечатываем символы '-' из переменной "so_far"

    so_far = 新的

    一个非常奇特的时刻，“so_far”变量正在通过“new”变量被保存，它反映了在这个猜词阶段被猜出的字母和破折号的真实位置。

    这种特殊的串珠串在串上，以猜测字母的形式出现。然后以这种方式进行，直到完全猜测或不猜测单词。

  2. 如果输入的字母包含在隐藏词中，则将其添加到行so_far中，其中写入了之前已经猜到的字母。
