How to quickly learn Python and Ruby frameworks coming from a PHP background

Question

I've been using CakaPHP and Kohanaphp but now I want to try out other frameworks from a more sophisticated OOP language for my next projects.

How can I learn the following frameworks quickly so I can immediately pick what to use:

• Pylons
• Sinatra
• Ramaze

Tutorials and examples from online resources would really be great.

For php developers who've already underwent this learning experience, please share yours.

Thanks

Answer 1

Regarding Pylons. There is a good introductory book written by one of the creators of Pylons. It is freely available online at http://pylonsbook.com/

Answer 2

For Ramaze, see:

• the website
• the wiki
• the book
• the mailing list
• the IRC channel

Answer 3

You can also learn about setting up Sinatra with Google's App Engine (via jRuby) here: http://code.google.com/p/appengine-jruby/

Fairly quick and easy setup.
