Question

import json

with open(file_name, 'r') as fp:
    obj = json.load(fp)

    text = obj['text']

    length = len(text)
    wordlist = text.split()
    wordfreq = []
    for w in wordlist:
        wordfreq.append(wordlist.count(w))

    lengthslova = len(wordlist)
    wordfind = 'in'
    indexword = wordlist.index(wordfind)

    findwordt = [[row[j] for row in findword] for j in range(lengthslova)]

    wordfind = "attacks"


    indexfreq = 0

    if indexword != ValueError:

    else: 
        indexfreq = 0
