Extracting information from the internet

[IWannaGetGood_1023]

Hiya, I'm very new to python, and I'm trying to make a python script that I can enter a word into, and it looks up the definition online. I was hoping someone knew how to do it - or if it is even impossible. I'm using Mu to make my scripts if that helps. Apologies if this is the wrong forum too.

Thanks!
