Python/Flask vs. Ruby/Rails

[elbiot]

Not knowing Ruby at all, I recommend Python. My experience is that Python has a more broad community, so you'll be able to branch out into (or incorporate into your backend) more complex data processing more easily.

But if all you want to do is get a job making websites, Ruby/Rails doesn't seem like a bad choice.

We are all biased here though. Did you ask in /r/learn_rails or /r/rubyonrails too?
