python怎么用循环删除字符串的某个字符

Question

题目如图

怎么保证猜过的词不重复出现？
我想的是每次猜正确后就把这个词从字符串中去除掉，但是不知道代码怎么写，以及while循环的条件是什么，或者有更好的思路吗？

Answer 1

import random
right = 0
num = 1
W = ['play', 'guess', 'english']
repeat = 'yes'
while num < len(W)+ 1:
    word = random.choice(W)
    word1 =word
    answer  = word
    a = ''
    for i in word:
        postion = random.randrange(len(word))
        a += word[postion]
        word = word[0:postion] + word[(postion+1):]
    print("乱序后的单词：", a)
    guess = input("输入你的猜测：")
    while guess != answer:
        guess = input("重新猜测：")
    print("猜对了")
    W.remove(word1)
    right += 1

print("一共猜对了{}个词".format(right))
print("游戏结束")

望采纳！谢谢
