Generating Diceware Passwords in Python

Today I'm going back to a theme from a post I wrote last year and looking at generating passwords with my favourite programming language. A tweet from Simon Brunning pointed me to Micah Lee's article at The Intercept and my first thought was to write a function to do this in Python. So here it is;

import random
word_dict = {}
passphrase = []
with open('diceware.wordlist.andy.txt') as f:
    for line in f.readlines():
        index, word = line.strip().split('\t')
        word_dict[int(index)] = word

for words in range(0, word_count):
    this_index = 0
    for position in range(0, 5):
        digit = random.randint(1, 6)
        this_index += digit * pow(10, position)
return ' '.join(passphrase)

In terribly bad form I've hard coded the diceware word list file name. I took the English word list and converted it to a plain text file for easier processing. The original will probably work just as well, I just haven't tested it.
