for RHEL 5, it's Python 2.4, for RHEL 6 it's Python 2.6.

from http://wiki.python.org/moin/PythonVsHaskell

List Comprehension Syntax:

Python's list comprehension syntax is taken (with trivial keyword/symbol modifications) directly from Haskell. The idea was just too good to pass up.

don't know for sure, it might be C++, Java, and now they have Go.

so, it's not as easy as python 2.x to 2.(x+1) and python 3.x to 3.(x+1). will every version update of Ruby will suffer as mush as Ruby 1.8 to 1.9?

what type of paper, Google's coding policy? there is a mail-list post, https://groups.google.com/forum/?fromgroups#!topic/unladen-s...

Python 2 to Python 3 is a big jump once in a lifetime. what about ruby 1.9 to ruby 2.0?

The PyPy team is amazing, for example Quora is now running on PyPy. and it's easy for a Python programmer run PyPy as an alternative(and hopefully fast) implementation.

Python 2.5 has any (and all) Python 2.3 has itertools so Google App Engine(2.5) should have both of them.

There is a PyCon video about Dropbox: PyCon 2011: How Dropbox Did It and How Python Helped http://pycon.blip.tv/file/4878722/

Sorry for my broken English, thanks for the elaboration.

yeah, http://www.python.org/dev/peps/pep-0374/

It's Chinese, which is a three-dimensional map of GuangZhou city, the labels are the names of places. and as rywang mentioned above, there is a 3d map http://sh.o.cn/ for ShangHai too

I am a native speaker(not born recently though). it still hard to speak or listen 'other' dialect, but more and more Mainland Chinese Speak mandarin instead of dialect， so it's more and more easy to communication.

Perhaps try this instead? http://nlp.stanford.edu/fsnlp/

for web (framework). Google App Engine still depends on Python 2, Django has some hesitates for the Python 3 port[1], the thread has some discuss about Python 3.2, peps 333(3) too. and have a Python 3 version itself is not the same thing it can be put into production as it's tried-and-true Python 2 version.

I think the real point is how many third party libs and packages support Python 3 yet. http://dev.pocoo.org/~gbrandl/py3.html

and Generator Expressions[1], a lazy version of list comprehensions [1]: http://www.python.org/dev/peps/pep-0289/

look at the "question tagged" and "Related Tags". maybe ruby is still focus "too much" on rails, on the other side, python has better overall ecosystem.

and IPython, it's a import part of NumPy/SciPy/MatplotLib family, offers a great many convenience features, such as tab-completion of python functions and a good help system. not to mention the new ZeroMQ messaging design(http://ipython.scipy.org/doc/nightly/html/development/messag...).

Maybe it can play the similar role in the MapReduce field like Sqlite in the Database world?
