Here is a recent action of google that has received at the moment 337,048 petitions: https://www.change.org/p/google-inc-google-put-palestine-on-your-maps Do you believe that Google is more ethical than Lebara? Ok you didn't suggest to use gmail (ie google) specifically So what do you suggest to people (like myself) who’s primary email is gmail and are incensed with such actions??

Does anyone know if there is a python module avaialbe to interact with this library (it is for downloading data down various Decompression computers so a bit of a specialist market) I already have an application that works fine (sub-surface) so this is more of a curiosity, delving into ctypes is not something I want to try just yet. -- According to Arkansas law, Section 4761, Pope's Digest: "No person shall be permitted under any pretext whatever, to come nearer than fifty feet of any door or window of any polling room, from the opening of the polls until the completion of the count and the certification of the returns."

How to extend a tuple of tuples?
by Frank Millman Sept. 9, 2016

Sept. 9, 2016

Hi all This should be easy, but I cannot figure it out. Assume you have a tuple of tuples - a = ((1, 2), (3, 4)) You want to add a new tuple to it, so that it becomes - ((1, 2), (3, 4), (5, 6)) The obvious way does not work - a += (5, 6) ((1, 2), (3, 4), 5, 6) I have discovered that there is something new in python 3.5 that does work - a = (*a, (5, 6)) ((1, 2), (3, 4), (5, 6)) But how would you have done it before? I know you can convert the outer tuple to a list, add the new tuple, and convert it back again. Is that the only solution? BTW, I do know that tuples are immutable, and that all of the above operations create a new tuple. Frank Millman

Because that's a tuple with one item, you need a trailing comma: py> len( ((5, 6),) ) 1 py> a + ((5, 6),) ((1, 2), (3, 4), (5, 6)) -- Steve “Cheer up,” they said, “things could be worse.” So I cheered up, and sure enough, things got worse.

Ultimately, asyncio and multithreading might well merge. It will be difficult for a programmer to decide in the beginning of the design which way to go as the programming models are almost identical.

Fwd: Fwd: Python freeze fails with warning: the use of `tempnam' is dangerous, better use `mkstemp'
by Alexander N. Moibenko Sept. 9, 2016

Sept. 9, 2016

Hello, when I build a binary with python 2.6 it builds without any problem. When I build with python 2.7 the build fails after warnings like: /opt/python/Python-2.7.12/Modules/posixmodule.o: In function `posix_tempnam': /opt/python/Python-2.7.12/./Modules/posixmodule.c:7578: warning: the use of `tempnam' is dangerous, better use `mkstemp' collect2: ld returned 1 exit status How this can be fixed? Thanks, Alexander
