Hola, Estoy intentando conectarme a twitter para recibir tweets, sin embargo algunos códigos que he bajado de internet, me indican que debo de instalar tweepy y matplotlib, lo hago y sigo recibiendo el mensaje de que no están instalados. tweepy no reporta problemas, lo invoco en la línea de comandos, todo bien, Igual con matplotlib requiere de varias dependencias (dateutils, numpy, tornado, etc, ya las instales) antes de su instalación, pero ya en el editor de Python, al ejecutar el código, me aparece el siguiente mensaje: ImportError: No module named 'matplotlib' alguna idea?

Convert int() to size_t in Python/C
by Marcos Dione 29 Apr '16

29 Apr '16

First of all, I'm not subbscribed to the list (too much traffic for me), so please CC: me in any answers if possible. I'm trying to add a new syscall to the os module: https://bugs.python.org/issue26826 One of the few missing parts is to cenvert a parameter, which would be a Python int object using PyArg_ParseTupleAndKeywords() to a size_t variable. For something similar, the 'n' format exists, but that one converts to Py_ssize_t (which is ssize_t, really), but that one is signed. One possible solution hat was suggested to me in the #python IRC channel was to use that, then test if the resulting value is negative, and adjust accordingly, but I wonder if there is a cleaner, more general solution (for instance, what if the type was something else, like loff_t, although for that one in particular there *is* a convertion function/macro). -- (Not so) Random fortune: Premature optimization is the root of all evil. -- Donald Knuth

Release schedule for Python 3.5.2
by Larry Hastings 29 Apr '16

29 Apr '16

I've been holding off on the hope that one or two bugs would get fixes. But those seem to have stalled. So I think it's time that we pushed out a 3.5.2. Maybe announcing a schedule will light a fire under some rumps. I put "Spring 2016" as the release date for 3.5.2 on the 3.5 release schedule PEP. Officially, spring ends--and summer begins--Tuesday June 21 at 12:24am EDT. However on the off chance that the PyCon sprints are productive, I want to hold off until those are done, and maybe give it a couple extra days for the dust to settle. Last sprint day is Sunday June 5th. So, bottom line, the RC will happen during spring, but the final release will technically be during summer. 3.5.2 RC 1 - tag Sat June 11, release Sun June 12 3.5.2 Final - tag Sat June 25, release Sun June 26 Any problems with that? Speak up now. //arry/

Inconsistency of PyModule_AddObject()
by Serhiy Storchaka 28 Apr '16

28 Apr '16

There are three functions (or at least three documented functions) in C API that "steals" references: PyList_SetItem(), PyTuple_SetItem() and PyModule_AddObject(). The first two "steals" references even on failure, and this is well known behaviour. But PyModule_AddObject() "steals" a reference only on success. There is nothing in the documentation that points on this. Most usages of PyModule_AddObject() in the stdlib don't decref the reference to the value on PyModule_AddObject() failure. The only exceptions are in _json, _io, and _tkinter modules. In many cases, including examples in the documentation, the successfulness of PyModule_AddObject() is not checked either, but this is different issue. We can just fix the documentation but adding a note that PyModule_AddObject() doesn't steal a reference on failure. And add explicit decrefs after PyModule_AddObject() in hundreds of places in the code. But I think it would be better to "fix" PyModule_AddObject() by making it decrefing a reference on failure as expected by most developers. But this is dangerous change, because if the author of third-party code read not only the documentation, but CPython code, and added explicit decref on PyModule_AddObject() failure, we will get a double decrefing. I think that we can resolve this issue by following steps: 1. Add a new function PyModule_AddObject2(), that steals a reference even on failure. 2. Introduce a special macro like PY_SSIZE_T_CLEAN (any suggestions about a name?). If it is defined, define PyModule_AddObject as PyModule_AddObject2. Define this macro before including Python.h in all CPython modules except _json, _io, and _tkinter. 3. Make old PyModule_AddObject to emit a warning about possible leak and a suggestion to define above macro.

support of the android platform
by Xavier de Gaye 26 Apr '16

26 Apr '16

Starting with API level 21 (Android 5.0), the build of python3 with the official android toolchains (that is, without resorting to external libraries for wide character support) runs correctly. With the set of patches described in the patches/Makefile file at [1], the cpython test suite runs[2] on the android x86 and armv7 emulators with only few errors[3]. Those errors are listed with their corresponding error messages, this may give a raw idea of the effort needed to support this platform. Xavier [1] https://bitbucket.org/xdegaye/pyona/src [2] To reproduce these results, follow the instructions found in INSTALL at https://bitbucket.org/xdegaye/pyona/wiki/install [3] https://bitbucket.org/xdegaye/pyona/wiki/testsuite
