After a year of Ruby programming I am in the middle of learning Python. The language part seems very easy (the "mechanics" of programming process) but "thinking in Python" part suggests that Ruby is a significantly higher level language. Once I will have spent some more time with Python I may realize I was wrong.

Why switch, you ask? Well, I am not switching, it's just another project where quality of language implementation matters, one area Ruby can't be proud of.
