PyDev 3.8.0 Released
What is PyDev? --- PyDev is an open-source Python IDE on top of Eclipse for Python, Jython and IronPython development. It comes with goodies such as code completion, syntax highlighting, syntax analysis, code analysis, refactor, debug, interactive console, etc. Details on PyDev: http://pydev.org Details on its development: http://pydev.blogspot.com What is LiClipse? --- LiClipse is a PyDev standalone with goodies such as support for Multiple cursors, theming and a number of other languages such as Django Templates, Kivy Language, Mako Templates, Html, Javascript, etc. It's also a commercial counterpart which helps supporting the development of PyDev. Details on LiClipse: http://brainwy.github.io/liclipse/ Release Highlights: --- * **Important**: PyDev requires Eclipse 3.8 or 4.3 onwards and Java 7! For older versions, keep using PyDev 2.x (use LiClipse: http://brainwy.github.io/liclipse for a PyDev standalone with all requirements bundled). * **Debugger** * It's now possible to **attach debugger to running process in Windows and Linux** (open debug perspective PyDev Attach to Process) * pep8 upgraded to 1.5.7 * Fixed issue in dialog shown when PyDev editor is opened which could lead to closing the IDE. * Selecting PyQT API version using sip.setapi no longer fails in debug mode (PyDev-452). * Code completion tries to get docstring definition from class before evaluating property (PyDev-412). * Internal error error when parsing file with wrong syntax: java.lang.ClassCastException for invalid dict (PyDev-411). * runfile was restored in pydevconsole (Ctrl+Alt+Enter is working again). * **Variables** and **Expressions** views working again when debugging interactive console (PyDev-446). * Pressing Shift to debug with Ctrl+F9 test runner now properly works in Linux (PyDev-444). * Fixed interpreter configuration when the interpreter prints something before actually running interpreterInfo.py (PyDev-448). * Fixed NullPointerException when debugging file without extension.

TextTest 3.27 - blackbox testing tool
Dear all, The latest release of TextTest includes - Support for parallel testing using EC2 cloud - Packaging and release process should now be smoother - Now integrates with Git as well and bzr and hg. - Performance data in HTML reports overhauled and many other things besides. Regards, Geoff Bache TextTest is a tool for automatic text-based functional testing. This means running a batch-mode executable in lots of different ways from the command line, and using the text output produced as a means of controlling the behavior of that application. As well as being usable standalone, it is an extendable framework for black-box testing written in Python. It's also useful as a test management tool wrapping some other test tool as a test runner.

See python docs on argparse - A read/eval print loop using custom keywords and syntax, if you want your program to be interactive. - you'll need to use readline to handle line editing - something to parse line input. PyParsing perhaps. Or some other lexical parser, or manually do the parsing you need to do with .split() or regular expressions. - possibly curses for doing screen output, though print() is probably sufficient.

TL;DR you need to think very hard about your problem definition and what you want to happen before you actually try to implement this. Always a good advice :) I'm actually implementing algorithm for someone else (in the bio world where I know very little about). See, THERE's your problem. You've got a scientist trying to make prescriptions for an engineering problem. He's given you a fuzzy description of the sort of thing he's trying to do. Your job is to turn that fuzzy description into a concrete, actual algorithm before you even write a single line of code, which means understanding what the data is, and what the desired result of that data is. Because the thing you keep trying to do, with all of its order dependencies fundamentally CANNOT be right, regardless of what the squishy scientist tells you. The histogram bin solution that everyone keeps trying to steer you towards is almost certainly what you really want. Epsilon is your resolution. You cannot resolve any information below your resolution limit. Yes, 1.49 and 1.51 wind up in different bins, whereas 1.51 and 2.49 are in the same one, but that's what it means to have a resolution of 1; you can't say anything about whether any given count in the 2, plus or minus a bit bin is very nearly 1 or very nearly 3. This doesn't require you to know the number of bins in advance, you can just create and fill them as needed. That said, you're trying to solve a physical problem, and so it has physical limits. Your biologist should be able to give you an order of magnitude estimate of how many bins you're expecting, and what the ultimate shape is expected to look like. Normally distributed? Wildly bimodal? Is the overall span of data going to span 10 epsilon or 10,000 epsilon? If there are going to be a ton of bins, you may be better served by putting 1/3 of a count into bins n-1, n, and n+1 rather than just in bin n; it's the equivalent of squinting a bit when you look at the bins.

Implementation languages are not part of the language definition and are
not limited to Python and C. Some CPython extension modules have used
Fortran (perhaps with a very thin C layer).
One way I can think of: apply inspect.signature. If it fails, the
function is not coded in Python. If it succeeds, pass a correct number
of args but invalid types/values (float('nan') for instance), catch the
exception, and see if the traceback contains a line of Python code from
the function. (But I am not sure what happens if the function was coded
in Python but the code is not available.)
As someone already asked, why?
Cython implemented native functions have a __code__ attribute, too. Their
current __code__.co_code attribute is empty (no bytecode), but I wouldn't
rely on that for all times either.
Meanwhile, Python classes and objects with __call__ methods have no
__code__ attribute.
Also, Python functions can call C functions, and many builtin functions
take Python functions as arguments.

pip install virtualenvwrapper complaining there's no module named core
I'm at a bit of a loss trying to figure out where this mysterious core module is. FWIW, this is a hosted server where python is 2.4, but 2.6 is available if named. Full steps were as follows: 1) Pull down get-pip.py as directed wget https://raw.github.com/pypa/pip/master/contrib/get-pip.py 2) Okay, raw.github.com serves a cert that wget doesn't like because the cert is assigned to just github.com (grumble) wget --no-check-certificate https://raw.github.com/pypa/pip/master/contrib/get-pip.py 3) Run it, specifying that I want things to get installed in my home/user directory: python2.6 get-pip.py --user 4) Okay, let's get me some virutalenv (works fine) pip2.6 install --user virtualenv 5) Okay, let's get me some virutalenvwrapper pip2.6 install --user virtualenvwrapper This is where things fall over (~/.pip/pip.log output below) with the inability to import a module named core. Where am I going wrong, or what am I missing? I have a nagging feeling that it's either a 2.4-vs-2.6 conflict, or possibly some PYTHONPATH (currently unset) issue that I missed. -tkc -- Downloading/unpacking virtualenvwrapper Running setup.py (path:/tmp/pip_build_tim/virtualenvwrapper/setup.py) egg_info for package virtualenvwrapper Installed /tmp/pip_build_tim/virtualenvwrapper/pbr-0.10.0-py2.6.egg Searching for pip Reading http://pypi.python.org/simple/pip/ Best match: pip 1.5.6 Downloading https://pypi.python.org/packages/source/p/pip/pip-1.5.6.tar.gz#md5=01026f87978932060cc86c1dc527903e Processing pip-1.5.6.tar.gz Running pip-1.5.6/setup.py -q bdist_egg --dist-dir /tmp/easy_install-CcQHLI/pip-1.5.6/egg-dist-tmp-8B3Dq1 warning: no files found matching 'pip/cacert.pem' warning: no files found matching '*.html' under directory 'docs' warning: no previously-included files matching '*.rst' found under directory 'docs/_build' no previously-included directories found matching 'docs/_build/_sources' Installed /tmp/pip_build_tim/virtualenvwrapper/pip-1.5.6-py2.6.egg /usr/local/lib/python2.6/site-packages/setuptools-0.6c9-py2.6.egg/setuptools/dist.py:245: UserWarning: Module pbr was already imported from /tmp/easy_install-7dd_Tz/pbr-0.10.0/pbr/__init__.py, but /tmp/pip_build_tim/virtualenvwrapper/pbr-0.10.0-py2.6.egg is being added to sys.path Traceback (most recent call last): File string, line 17, in module File /tmp/pip_build_tim/virtualenvwrapper/setup.py, line 7, in module pbr=True, File /usr/local/lib/python2.6/distutils/core.py, line 113, in setup _setup_distribution = dist = klass(attrs) File build/bdist.linux-i686/egg/setuptools/dist.py, line 223, in __init__ File /usr/local/lib/python2.6/distutils/dist.py, line 270, in __init__ self.finalize_options() File build/bdist.linux-i686/egg/setuptools/dist.py, line 256, in finalize_options File build/bdist.linux-i686/egg/pkg_resources.py, line 1913, in load ImportError: No module named core Complete output from command python setup.py egg_info: Installed /tmp/pip_build_tim/virtualenvwrapper/pbr-0.10.0-py2.6.egg Searching for pip Reading http://pypi.python.org/simple/pip/ Best match: pip 1.5.6 Downloading https://pypi.python.org/packages/source/p/pip/pip-1.5.6.tar.gz#md5=01026f87978932060cc86c1dc527903e Processing pip-1.5.6.tar.gz Running pip-1.5.6/setup.py -q bdist_egg --dist-dir /tmp/easy_install-CcQHLI/pip-1.5.6/egg-dist-tmp-8B3Dq1 warning: no files found matching 'pip/cacert.pem' warning: no files found matching '*.html' under directory 'docs' warning: no previously-included files matching '*.rst' found under directory 'docs/_build' no previously-included directories found matching 'docs/_build/_sources' Installed /tmp/pip_build_tim/virtualenvwrapper/pip-1.5.6-py2.6.egg /usr/local/lib/python2.6/site-packages/setuptools-0.6c9-py2.6.egg/setuptools/dist.py:245: UserWarning: Module pbr was already imported from /tmp/easy_install-7dd_Tz/pbr-0.10.0/pbr/__init__.py, but /tmp/pip_build_tim/virtualenvwrapper/pbr-0.10.0-py2.6.egg is being added to sys.path Traceback (most recent call last): File string, line 17, in module File /tmp/pip_build_tim/virtualenvwrapper/setup.py, line 7, in module pbr=True, File /usr/local/lib/python2.6/distutils/core.py, line 113, in setup _setup_distribution = dist = klass(attrs) File build/bdist.linux-i686/egg/setuptools/dist.py, line 223, in __init__ File /usr/local/lib/python2.6/distutils/dist.py, line 270, in __init__ self.finalize_options() File build/bdist.linux-i686/egg/setuptools/dist.py, line 256, in finalize_options File build/bdist.linux-i686/egg/pkg_resources.py, line 1913, in load ImportError: No module named core Cleaning up...

http://en.wikipedia.org/wiki/Leap_year#Algorithm
Me trying to look at the algorithm, it would lead me to try something
like:
if year % 4 !=0:
return False
elif year % 100 !=0:
return True
elif year % 400 !=0:
return False
Since it is a practice problem I have the answer:
def is_leap_year(year):
return ((year % 4) == 0 and ((year % 100) != 0 or (year % 400) == 0))
I didn't have any problem when I did this:
if year % 400 == 0:
print (Not leap year)
elif year % 100 == 0:
print (Leap year)
elif year % 4 == 0:
print (Leap year)
else:
print (Not leap year)
Which is, except for language syntax to state it, exactly the same as is
quoted for this problem in the original KR C manual. Is there anything
new?

[issue22501] Optimise PyLong division by 1 or -1
Stefan Behnel added the comment: Here is an incremental patch that adds fast paths for adding and subtracting 0. Question: the module calls long_long() in some places (e.g. long_abs()) and thus forces the return type to be exactly a PyLong and not a subtype. My changes use a plain incref+return input value in some places. Should they call long_long() on it instead? -- Added file: http://bugs.python.org/file36734/add_sub_0_fast_path.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22501 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue22501] Optimise PyLong division by 1 or -1
Stefan Behnel added the comment: I reran the fractions benchmark over the final result and the overall gain turned out to be, well, small. It's a clearly reproducible 2-3% faster. That's not bad for the macro impact of a micro-optimisation, but it's not a clear argument for throwing more code at it either.

[issue22445] Memoryviews require more strict contiguous checks then necessary
Stefan Krah added the comment: Ok, here's my take on the situation: 1) As far as Python is concerned, shape[0] == 1 was already special-cased, so people could not rely on canonical Fortran or C strides anyway. 2) Accessing an element via strides should be done using PyBuffer_GetPointer(), which can of course handle non-canonical strides. 3) Breakage will only affect NumPy users, since practically no one else is using multidimensional arrays. Regarding your option 2b): I think it may be confusing, the buffer protocol is already so complicated. So, I think purity wins here. If you are sure that all future NumPy versions will ship with precise contiguity checks, then I'll commit the new patch in 3.5 (earlier versions should not be changed IMO). I've moved the checks for 0 in shape[i] to the beginning (len == 0). I hope there are no applications that set len incorrectly, but they would be severely broken anyway. -- stage: - patch review versions: +Python 3.5 Added file: http://bugs.python.org/file36738/issue22445.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22445 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Ezio Melotti added the comment: As for output buffering, may be replace sys.stdout by file-like object which flushes its buffered content to original stdout on failure and discard it on success. This is what the --buffer option is already supposed to do (I only found out about it thanks to this issue, the name is not very indicative of what it does...). IIUC what Antoine is suggesting is having a more fine-grained control of the buffering, and the ability to set it from individual test cases rather than using a global command line flag or unittest.main(buffer=True) (which is only used while executing the test file directly). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22197 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
