Iteration 2

to run rss parser on your computer you need to:

1. clone repository from https://github.com/ElizabethUniverse/FinalTaskRssParser
2. $cd final_task
3. $python setup.py sdist upload
4. $cd dist
5. $pip install rss_reader-1.1.tar.gz
6. run $rss_reader https://news.yahoo.com/rss --limit 2 --verbose

Iteration 3

News is stored in the csv cache in following format and with tab delimiter.

date title link article list_links

Now we are searching for the news in the cache with O(n) complexity. But in the near future we plan to optimize this process.

If you want to receive news for the 15/11/2019, please enter the following command in the command line

$python rss_reader.py https://news.yahoo.com/rss --date 20191115

--date argument works without internet connection and with --verbose, --json, --limit LIMIT arguments the same way.

##Iteration 4

News can be converted to pdf or html.

If you want to convert news to pdf:

$python rss_reader.py https://news.yahoo.com/rss --to-pdf path

to html:

$python rss_reader.py https://news.yahoo.com/rss --to-html path
