I've been trying to teach myself Python recently, with mixed success. (Recently, I have been a little seduced by the availability of resources and community around Ruby, since my interest is mostly in doing things on the web - so e.g. Rails vs. Django, even though I conceptually like the later, for some logistical reasons I am finding the former to be a little tempting to experiment with more.)
However, a principal question I still have concerns the different versions of Python. [http://wiki.python.org/moin/Python2orPython3]
I have read the Wiki and understand some of the differences, or lack-of-differences, but am still unclear. For example, I know some servers or services (eg Google App Engine) are at one version, while others are at another. Should I be concerned about any of this? Is there any reason to try to use Python 3 at present? Etc?
Thanks for any insights here!
