使用枚举查找带有字母"x"的所有单词的索引

Question

如何使用enumerate帮助查找包含'x'的所有单词的索引

谢谢

wordsFile = open("words.txt", 'r')
words = wordsFile.read()
wordsFile.close()
wordList = words.split()
indices=[]
for (index, value) in enumerate(wordList):
    if value == 'x':
print("These locations contain words containing the letter 'x':n",indices)

Answer 1

你的代码差不多完成了:

for (index, value) in enumerate(wordList):
    if 'x' in value:
        indices.append(index)

检查每个单词中是否有x。如果是，则将索引添加到indices。
