Slightly more difficult, I would say. The syntax is a bit more complicated
and you have to learn about iterators sooner (not that there is anything
wrong with that :).

Nah. It's the same. You might argue that Ruby takes OO a bit
further, while Python is more of a mix of OO and procedural style. But this
is mostly on superficial issues, such as whether to call s.length
or length(s) (yes I know that Python now supports the former) and whether
self is implicit (it is in Ruby).

Python has better documentation (at least if you don't read Japanese), more
third party modules, is more mature, is faster (in my experience), has no
fundamental syntax problems. (In Ruby's more flexible syntax --- the semantics
of a program can, in some weird situations, change if you put a space in the
That said, I should also say that I love Ruby, for its consistent OO'ness,
creative use of iterators, accessor functions, conciseness, ease of extension,
mix-ins, etc. I cannot see why anyone would want to avoid it.
BTW, I wish that people who don't know what they are talking about would stop
claiming that Ruby is too Perl-like to use: "I've never actually programmed in
Ruby, but it looks a lot like Perl, so it must be bad." While Ruby has borrowed
some features from Perl, it hasn't borrowed any of the bad and ugly features
Trust me, programming in Ruby is NOTHING like programming in Perl.

I'm not sure what it is you find difficult with OO Python, the differences
are mostly syntactical. But the "pickaxe" book is great reading, I can
really recommend it.

Ah, but time spent learning is never wasted. And programming languages never
get jealous. Get acquainted with them both and then follow your heart.
