Ruby has unconstrained lambdas for a start and a much more composable, expressive syntax facilitating the creation of elegant DSLs. Rails, Chef and other Ruby projects lean on this feature. The goals of Ruby's creator, Matz, were more idealistic and artistic than those of Python's creator, Guido, whose values are more pragmatic and math-focused. Matz took inspiration from Perl, Smalltalk and Lisp whereas Guido set out to solve a much more local, project-based problem when he created Python.
