Use enumerate to find indices of all words with letter 'x'

Question

How use enumerate to help find the indices of all words containing 'x'

Thank you

wordsFile = open("words.txt", 'r')
words = wordsFile.read()
wordsFile.close()
wordList = words.split()

indices=[]

for (index, value) in enumerate(wordList):
    if value == 'x':

It turned out I just needed to use the append function. Thank you for your suggestion though! — CV88, Sep 15 '16 at 01:15
Do you have one word per line? You also need `in` as unless the word was `x` then you would never get a match. — Padraic Cunningham, Sep 15 '16 at 01:16

Your code is almost complete:

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

This checks, for every single word, if there is an x in it. If so, it adds the index to indices.
