This week, each one of you has a homework assignment ... - Tyler Durden (Fight club)
Given our RSS feed what tags does PyBites mostly use and which tags should be merged (based on similarity)?
$ python tags.py * Top 10 tags: python 10 learning 7 tips 6 tricks 5 github 5 cleancode 5 best practices 5 pythonic 4 collections 4 beginners 4 * Similar tags: game games challenge challenges generator generators
Start coding by forking our challenges repo:
$ git clone https://github.com/pybites/challenges
If you already forked it sync it:
# assuming using ssh key $ git remote add upstream email@example.com:pybites/challenges.git $ git fetch upstream # if not on master: $ git checkout master $ git merge upstream/master
Use one of the templates:
$ cd 03 $ cp tags-help.py tags.py # or: $ cp tags-nohelp.py tags.py # code # run the unittests (optional) $ python test_tags.py ... ---------------------------------------------------------------------- Ran 3 tests in 0.155s OK
Requirements / steps
As we update our blog regularly we provided a recent copy of our feed in the 03 directory: rss.xml. We also provided a copy of tags.html for verification (used by unittests in test_tags.py).
Both templates provide 3 constants you should use:
TOP_NUMBER = 10 RSS_FEED = 'rss.xml' SIMILAR = 0.87
Rest is documented in the methods docstrings. Again use tags-help.py if you need more guidance, tags-nohelp.py is for the more experienced and/or if you want more freedom. Same goes for tests: use them if you need them.
Talking about freedom feel free to use our live feed but then the tests will probably break.
Hint: for word similarity feel free to use NLTK, or your favorite language processing tool. However, stdlib does provide a nice way to do this. Using this method we came to 0.87 as a threshold to for example not mark 'python' and 'pythonic' as similar.
Remember: there is no best solution, only learning more and better Python.
Enjoy and we're looking forward reviewing on Friday all the cool / creative / Pythonic stuff you come up with.
