How can I optimize this Python code to generate all words with word-distance 1?

Question

Profiling shows this is the slowest segment of my code for a little word game I wrote:

def distance(word1, word2):
    difference = 0
    for i in range(len(word         


        

Answer 1

Try this:

def distance(word1, word2):
  return sum([not c1 == c2 for c1, c2 in zip(word1,word2)])

Also, do you have a link to your game? I like being destroyed by word games
