I presume this is:
Ruby on Rails (i.e. the Rails framework, using Ruby as the programming language)
vs
Django (i.e. the Django web framework, using Python as the programming language)
Both of these frameworks are Model View Controller (MVC) frameworks, so they are both capable of web applications and web pages.
Therefore, your decision is really "Python or Ruby".
Both Ruby and Python are object-oriented languages and are easy to get into... they both have quick-start guides here:
http://www.ruby-lang.org/en/documentation/quickstart/
http://wiki.python.org/moin/BeginnersGuide
I think Ruby has the edge in terms of simple documentation and ease of use - as long as you are happy to abide by the rules that the language enforces (which aren't necessarily a bad thing by the way).
