But I'm kinda blown away with the hype of Ruby, I've now started to read some tuts about both of them.
Frankly, I've heard way more hype over Ruby frameworks like Rails than Ruby itself. Don't let hype determine anything.
Just go through any of the for-beginners-who-already-know-basic-programming for Python, Ruby, or whoever, and I think their styles are different enough that you'll immediately like one over the other (maybe not).
Certainly you can do plenty in Python. There are a gazillion and one frameworks, styles, applications...
For Python you'll probably be most intereted in PyJamas.
I remember reading about client-side Ruby implementations (as text/rtml) but don't know of any specific project being worked on.
