[off-topic] If PHP and Javascript are the only programming languages you know, you really should experiment with at least one or two others. It comes easier than expected. For example, check out http://www.diveintopython.net/toc/index.html. You can't know what you're missing out on until you try something new.
But if you already know PHP and Javascript, why not try branching out a bit instead of learning Python, which is very similar overall? How about a lispy language like Racket, or a statically typed functional language like OCaml, or a 'big' mainstream applications language like Java?
That's the point. Python is similar to php/js (which is why it's easy to pick up), but in contrast to them it is extremely well designed (imho). You suddenly understand how many of the quirks you have to go through every day coding in php/js are in fact artifacts of these two inconsistent poorly designed (imho) languages rather than programming as a whole.
