python中怎么在循环里删除字符串中的某个确定字符

题目如图

怎么修改这个代码让每次猜过的词不再出现？while循环条件要怎么写

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
