The Data

Run git pull in your sd212 directory.

You should see a new folder for this homework with two files:

• 10k-words.txt is a list of 10,000 common English words (source)

• friends.py is a working Python program that you will modify.

Starter code

The friends.py program looks through that list of words and prints out all pairs of words that are “friends”, meaning that the two words are exactly the same except for their 2nd and 6th letters. For example, “mAssiVe” and “mIssiLe” are friends.

Your task

If you run friends.py as-is, it works correctly to find all friend words, but takes a little while, probably about 30 seconds.

Improve the code so that it uses Python multiprocessing and 5 concurrent calls to check_words so that it gets all the same results (maybe in a different order), but runs faster.

Submit command

To submit files for this homework, run one of these commands:

submit -c=sd212 -p=hw17 friends.py
club -csd212 -phw17 friends.py
