Code description

• Code uses argparse module.
• Codebase covered with unit tests with at 90% coverage.
• Any mistakes are printed in human-readable error explanation. Exception tracebacks in stdout are prohibited.
• Docstrings are mandatory for all methods, classes, functions and modules.
• Code corresponds to pep8 (used pycodestyle utility for self-check).
• Feedparser module is used for rss parsing;
• There are several bots for parsing news: default bor for unimplemented RSS urls and custom bots (yahoo, tut) with detailed approach to parsing.

Code self-checking

Use ./pycodestyle.sh to check the code corresponding to pep8 (pycodestyle package must be installed)

Iteration 5

Defined class Colors with stored attributes for text color. Without console arg --colorize class initialises with no colors, but with --colorize class initialises with colors. News classe use Colors's attributes to print their text

Iteration 6

Web app is a simple flask app that do the only think - launch rss_reader's modules. That's why there is no rest api and 'big' DB.

To run server you may create a docker image: docker build . -t flask:v1

And run it in a docker container: docker run -p 5000:5000 flask:v1

App will be accessible on the 0.0.0.0:5000 socket. BTW those commands will install rss_reader utility.

Installing

Use the script ./install_util.sh.

• it will install all dependencies and launch the server in a docker container.
• to use rss_reader utility enter: python -m rss_reader

If you don't have docker server will not be launched. But you can do it manually by entering (in the root folder 'PythonHomework'): python -m server
