2. here is a link to the file if it helps http://vlm1.uta.edu/~athitsos/courses/cse1310_summer2013/assignments/assignment8/word_list.txt

Answer 1

import random

with open('word_list.txt', 'r') as f:
    words = [word.rstrip() for word in f if len(word) > 5]

print random.choice(words)

As @ashwini-chaudhary correctly pointed out, word on each step of iteration has newline \\n at the end - that's why you need to use rstrip() .

Answer 2

Assuming each word is on it's own line such as:

word
word2
word3
...

then you can do this:

from random import choice
with open("word_list.txt") as file:
    print choice([line.rstrip() for line in file if len(line) > 5])
