Get the details of any ongoing anime using myanimelist
Code is very simple but is very helpful in case you need the dates. There might be a problem with a few anime series and this is most probably because of their database and manual sequence. Don't worry much because the newest additions work fine. Just copy the link of episodes menu of your anime and replace "url" with it.
There you go! For Python 3.x, new script added - "anime-list.py"
