I've been following the saga of Python 3.x and have watched the 3.x features gradually getting back-ported to the 2.x line. Most of the libraries I use haven't been ported and some (e.g. Twisted) seem covertly or overtly hostile to 3.x to varying degrees. At any rate, there has been very little movement towards compatible versions of...
The Python 2.7 update note says: A new version of the io library, rewritten in C for performance. I've played with Python 2.7 a bit, but I don't see any performance gain: >>> from timeit import Timer >>> t = Timer('f = open("E:\\db.txt", "r"); f.read(); f.close()') >>> t.timeit(10000) And the result: Python 2.6.5 -- 12....
I am learning to program in Python and we have version 2.7 installed at work. Whenever I try to dive deep into Python, I never liked the dea of diving into a deprecated version (2.7). My work is not ready for 3.0 just yet. My question is : I want to write code in 2.7 which can easily be converted to 3.0 using 2to3. Honestly, I want to s...

I've come across a bug in Python (at least in 2.6.1) for the bytearray.fromhex function. This is what happens if you try the example from the docstring: >>> bytearray.fromhex('B9 01EF') Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: fromhex() argument 1 must be unicode, not str This example works f...
I'm extending the python 2.7 unittest framework to do some function testing. One of the things I would like to do is to stop all the tests from running inside of a test, and inside of a setUpClass method. Sometimes if a test fails, the program is so broken it is no longer of any use to keep testing, so I want to stop the tests from runn...
I want to completely remove Python 2.7 from my Mac OS X 10.6.4. I managed to remove the entry from the PATH variable by reverting my .bash_profile. But I also want to remove all directories, files, symlinks, and entries that got installed by the Python 2.7 install package. I've got the install package from http://www.python.org/. What di...
I'm using python 2.7, and trying to run some CPU heavy tasks in their own processes. I would like to be able to send messages back to the parent process to keep it informed of the current status of the process. The multiprocessing Queue seems perfect for this but I can't figure out how to get it work. So, this is my basic working exampl...

We've been using M2crypto with Python 2.6 for Windows (32-bit) for some time with great success. We used one of the user contributed setups to install M2crypto in our development environments. We would like to move to Python 2.7, but noticed there are no pre-built Python 2.7 setups for m2crypto. Questions: Is M2crypto 0.20.2 compatibl...
Any recommendations on an AES encryption library that's compatible with Python 2.7 for Windows? In the past we've used m2crypto with Python 2.6, but there's no version of m2crypto for Python 2.7 and our attempts to build a version from source have failed. Thank you, Malcolm ...
