Error when trying to obtain a random word

[RapidCompiler]

Description

Code

from django.shortcuts import render
from random_word import RandomWords

def hangman(request):
    return render(request,'hangman/plain_page_2.html')

def hangman_org(request):    
    r = RandomWords()
    guess = request.POST.get('guess')
    w_len = request.POST.get('w_len')
    lst = []
    word = r.get_random_word(hasDictionaryDef="true",minLength=w_len,maxLength=w_len)
    count=0
    word = word.lower()
    length = len(word)
    for i in range(1,length+1):
        lst.append(i)
    context = {
        'guess' : guess,
        'lst' : lst,
        'hmword' : word
        }
    return render(request,'hangman/plain_page.html',context)

Expected behavior A Random Word must be generated without encountering the above mentioned error.

Environment (please complete the following information):

• OS: Windows
• Python 3.7

I even tried generating a random word outside the Django application. The same error was encountered.
