numba 0.7.1: bugfix release + random package
Numba 0.7.1 is a bugfix release which brings bug fixes such as the array slicing bug, but it also brings us closer to Python 3 compatibility thanks to Hernan Grecco. The release also brings the 'numba.random' package, thanks to Travis Oliphant. It allows you to use fast random number generators from randomkit provided in NumPy, directly from numba code. An example can be found here: https://github.com/numba/numba/blob/master/numba/tests/support/random/test_random_gibbs.py#L13 Download: https://pypi.python.org/pypi/numba/0.7.1 Documentation: http://numba.pydata.org/numba-doc/0.7/ Github: https://github.com/numba/numba Numba == Numba is an just-in-time specializing compiler for Python and NumPy code to LLVM for annotated functions (through decorators). It's goal is to seamlessly integrate with the Python scientific software stack and provide optimized native code and integration with native foreign languages.

But yes, I will concede that a single pickled int is relatively readable. But that certainly isn't always the case: py pickle.dumps([]) '(lp0\n.' py pickle.dumps([None]) '(lp0\nNa.' For even a *slightly* more complex example, the pickle turns into noise.

Compare pickle's 1400 lines with the dozen or so lines I provided. That is all that I meant by overkill. More importantly, if the code evolve and you need to store 2 integers, or a tuple or anything else that is pickable, it costs you 0 dev if you're using pickle. Sure.

RE: Reversing bits in a byte
Sorry, the subject line was for a related question that I decided not to ask, I forgot to change it when I changed my email. I've changed it now! I'm using Python 3.3 on Windows with the pydicom module (http://code.google.com/p/pydicom/). Using pydicom, I've ended up with a bytes object of length (512*512/8 = 32768) containing a 512x512 1-bit bitmap (i.e. each byte represents 8 pixels of either 1 or 0). When I print this to screen I get: 'b\x00\x00\x00.' I can unpack this to a tuple of the integer representations of binary data, but that doesn't really help as presume I need the binary (8 digit) representation to be able to translate that into an image. I wasn't sure which GUI library to use, so haven't specified one. As it's Python 3, Tkinter is available. I also have matplotlib and numpy installed, and PIL. Ideally, I'd like to be able to access the pixel data in the form of a numpy array so that I can perform image-processing tasks on the data. So now that I've explained myself slightly more fully, does anyone have any thoughts on how to do this?

RE: Reversing bits in a byte
Further to my earlier reply to Dave: I'd like to either display the image in a GUI, or save it in a format that can be opened easily in Windows (like a PNG or a 24-bit BMP). I know the dimensions as it's coming from the header of a DICOM file. I'm trying to analyse DICOM images where an 'overlay' image is stored as a bitmap in the header information. So the bitmap data is one DICOM tag (6000,3000) and the height and width of the overlay are in two other tags (6000,0010) and (6000,0011).

Make sure you don't ever load a module by more than one name, or you'll end up with a mess. And that includes the original script, which is loaded by the name '__main__' You also should avoid any circular import, as it can be very tricky to deal with them. The two programs are separate, there is no fear of a circular import. Also, I need only a function to get access to the objects in the other module so the import is inside the function... no fear of ending up in a mess. Thanks.

Matplotlib Slider Widget and changing colorbar threshold
I am currently trying to work on a program that will allow the user to display their dataset in the form of a colormap and through the use of sliders, it will also allow the user to adjust the threshold of the colormap and thus update the colormap accordingly. The best to describe this would be through the use of a picture: ![enter image description here][1] [1]: http://i.stack.imgur.com/1T9Qp.png This image shows how the colorbar should look before (the image on the left) and after (the image on the right) the adjustment. As the threshold values of the colrobar are changed, the colormap would be updated accordingly. Now I am mainly using matplotlib and I found that matplotlib does support some widgets, such as a slider. However the area I need help in is devising a piece of code which will update the colorbar and colormap (like the way shown in the picture above) when the slider is adjusted. I was wondering if anyone has done this before and might have a piece of code they would be willing to share and might have pointers as to how this can be achieved. -- http://mail.python.org/mailman/listinfo/python-list

image transforming web proxy?
I stumbled upon an old FFT tutorial on astro.berkeley.edu website whose images are in xbm format. Neither Chrome nor Firefox knows how to display X bitmap format and for Chrome at least, I've been unable to find an extension to do the conversion (didn't hunt for a FF extension). I can clearly download the whole kit-n-kaboodle, use any of a number of different tools to convert the images from xbm to png, then view things locally. I finally figured out that Opera supports xbm and downloaded it. I wonder though, if there is a Python-based web proxy out there which can transparently transform obsolete image formats like xbm into png, jpeg, presumably using PIL?

You can test yourself to see that numpy is 10x faster for large arrays: Python 2.7 on Linux: $ python -m timeit -s 'import random' -- '[random.uniform(0, 5) for x in range(1000)]' 1000 loops, best of 3: 729 usec per loop $ python -m timeit -s 'import random' -- '[random.random() * 5 for x in range(1000)]' 1000 loops, best of 3: 296 usec per loop $ python -m timeit -s 'import numpy' -- 'numpy.random.uniform(0, 5, 1000)' 1 loops, best of 3: 32.2 usec per loop I would use numpy for this mainly because if I'm creating arrays of random numbers I probably want to use them in ways that are easier with numpy arrays.

Perhaps an example will help. Let's say we have a variable called x that we initialise with x = 2 Here's a line of code that prints 2*x: print(2 * x) This will print out 4 but that's not what you want. Here's a function that prints its argument multiplied by 2: def double(y): print(2 * y) Now we have a function and we can call it with double(x) so that it prints 4. Again, though, you didn't want to print it. You wanted to *return* the value. So here's a function that *returns* 2 times its argument: def double(x): return 2 * x Now if we do z = double(x) z will have the value 4. You can check this with print(z) Try the code above and see if you can apply the same principles to your problem. Oscar -- http://mail.python.org/mailman/listinfo/python-list

You can test yourself to see that numpy is 10x faster for large arrays: Python 2.7 on Linux: $ python -m timeit -s 'import random' -- '[random.uniform(0, 5) for x in range(1000)]' 1000 loops, best of 3: 729 usec per loop $ python -m timeit -s 'import random' -- '[random.random() * 5 for x in range(1000)]' 1000 loops, best of 3: 296 usec per loop $ python -m timeit -s 'import numpy' -- 'numpy.random.uniform(0, 5, 1000)' 1 loops, best of 3: 32.2 usec per loop I would use numpy for this mainly because if I'm creating arrays of random numbers I probably want to use them in ways that are easier with numpy arrays. There's also a chance the OP might benefit more generally from using numpy depending on what they're working on. Oscar I don't think numpy is unreasonable for you or me. I just started learning it recently, and I'm pretty jazzed about its possibilities. I obtained an app for work that uses it, and now it's up to me to maintain it, so learning it is a good idea for me regardless. Now I'm starting to fantasize about other things I could do with it. But the OP appears like a pretty basic beginner, and I really think that for such a entry-level knowledge scale, we should stick to the standard library until they're ready to take on more sophisticated tasks. Premature Optimization is the analogy that comes to mind. -- http://mail.python.org/mailman/listinfo/python-list

[issue17404] ValueError: can't have unbuffered text I/O for io.open(1, 'wt', 0)
New submission from Robert Collins: The io library rejects unbuffered text I/O, but this is not documented - and in fact can be manually worked around: binstdout = io.open(sys.stdout.fileno(), 'wt', 0) sys.stdout = io.TextIOWrapper(binstdout, encoding=sys.stdout.encoding) will get a sys.stdout that is unbuffered. Note that writing to a pipe doesn't really need to care about buffering anyway, if the user writes 300 characters, the codec will output a single block and the IO made will be one write: This test script: import sys import io stream = io.TextIOWrapper(io.open(sys.stdout.fileno(), 'wb', 0), encoding='utf8') for r in range(10): stream.write(u'\u1234'*500) When run under strace -c does exactly 10 writes: so the performance is predictable. IMO it doesn't make sense to prohibit unbuffered text write I/O. readers may be another matter, but that doesn't suffer the same latency issues. -- messages: 184025 nosy: rbcollins priority: normal severity: normal status: open title: ValueError: can't have unbuffered text I/O for io.open(1, 'wt', 0) type: behavior versions: Python 2.6, Python 2.7, Python 3.1, Python 3.2, Python 3.3, Python 3.4, Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17404 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17405] Add _Py_memset_s() to securely clear memory
New submission from Christian Heimes: Compilers like GCC optimize away code like memset(var, 0, sizeof(var)) if the code occurs at the end of a function and var is not used anymore [1]. But security relevant code like hash and encryption use this to overwrite sensitive data with zeros. The code in _sha3module.c uses memset() to clear its internal state. The other hash modules don't clear their internal states yet. There exists a couple of solutions for the problem: * C11 [ISO/IEC 9899:2011] has a memset_s() function * MSVC has SecureZeroMemory() * GCC can disable the optimization with #pragma GCC optimize (O0) since GCC 4.4 * [2] contains an example for a custom implementation of memset_s() with volatile.

And it's even worse with python 2.7:: import io as io buffer = io.BytesIO() output = io.TextIOWrapper(buffer, encoding='idna') output.write(www.somesite.com) Traceback (most recent call last): File stdin, line 3, in module TypeError: must be unicode, not str -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17404 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17399] test_multiprocessing hang on Windows, non-sockets
Richard Oudkerk added the comment: Both 3.2 and 3.3 give essentially the same traceback as 3.2 did before, both with installed python and yesterdays debug builds. It looks like on your machine socket handles are not correctly inherited by child processes -- I had assumed that they always would be. I suppose to fix things for 3.2 and earlier it would be necessary to backport the functionality of socket.socket.share() and socket.fromshare() from 3.3. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17399 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue17232] Improve -O docs
Terry J. Reedy added the comment: I corrected my copy of the .diff. Since this issue is so far focused on removing the false optimize claim, hiding .pyx info is a new sub-issue. I will follow whatever the consensus is, but since this is a cpython-specific doc and help, I would prefer to give complete info. In fact, I would like to add 'stored in __pycache__' or even 'hidden away in __pycache__', the latter to suggest that most people should generally forget about them. On Windows, _xxx files like __pycache__ appear in both Command Prompt dir and Explorer file listings, so beginners need to known that __cache__ is both normal and ignorable. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17232 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue14243] tempfile.NamedTemporaryFile not particularly useful on Windows
Piotr Dobrogost added the comment: @sbt (...) and it seems that on Windows open() is more or less implemented as a wrapper of sopen(..., ..., SH_DENYNO, ...). So the only reason that trying to reopen a NamedTemporaryFile fails on Windows is because when we reopen we need to use O_TEMPORARY. Could you elaborate on this? What's the relation between SH_DENYNO argument to sopen() and O_TEMPORARY flag? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue14243 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
