In fact, that's *often* true. Maybe it's unpleasant for the person the jab is aimed at; maybe it feels awkward for you, as an onlooker. But for the good of python-list, Nikos has to be told that putting minimal effort into his questions is a bad thing, and if you're going to say that, may as well say it in a funny way. Plus, Steven was making a solid point, too. So if you want Nikos to be ignored by anyone who can't be completely friendly, what you'll end up with is materially less content on the list.

You do not seriously believe that that needs to be spelled out? Your context adds nothing. The only thing that the context would add, is that in this specific case you think that the end justifies the means but it doesn't explain in any way on what grounds you think so. Those that took Nikos to task earlier for his behaviour probably though their end justified the means too. So yes, if you don't want to give the impression that you are simply ad hoccing what you personnally don't have a problem with, you'd better spell a few things out. I would not, for instance, destroy Nikos's server, data, or access to either, to make a point; and history will confirm this. No it doesn't. No? He gave me his root password - check the list archives. I did none of the above three destructive actions (nor any other destructive action), even though it would have made my point much stronger to do so. You behaved in a way some people clearly thought of a questionable. So for those people you have established you are prepared to exhibit questionable behaviour to make your point. So I think there are a number of people who will think of you as not trustable enough to withhold the behaviour in question here, when you think it would be necessary to make your point.

Re: Tryign to send mail via a python script by using the local MTA
Look, i want this to stop. Open your own thread and discuss this if you like. This is a thread i opened for a specific question and all i see its irrelevant answers. Hi Ferrous, The problem is not in your Python code. You can debug it from the command line by typing the 'echo ... | mailx' command your Python code is executing. Somewhere on your local SMTP or on Google's SMTP, your message is not being processed the way you want it. There are many things that could cause this -- SPF, DKIM, reverse DNS not being correct, the From address being 'faked', or one of about a hunderd other factors. It's most likely an issue in your local SMTP server's configuration. You'll have to dive into the logs and do some research on how SMTP works nowadays to find out what's happening. But think about this: if I could send mail as nikos.gr...@gmail.com, just by typing a shell command, how could we ever trust e-mail to be from who it really is? What if I send mail as barack.ob...@whitehouse.gov? What you're doing may look like spam from Google's point of view, and that's why I think you're not receiving the message. -- https://mail.python.org/mailman/listinfo/python-list

Is %z broken for return values of time.gmtime()?

I’m using a date near to today to rule out any peculiarities with dates that are long in the past. Using a date at which DST was active yields the same result: time.strftime(%F %T %z, time.gmtime(40.5 * 365 * 86400)) '2010-06-22 12:00:00 +0100' Why is my OS’s time zone used for formatting a struct_time with the UTC time zone?

On 16/9/2013 00:05, Mohsen Pahlevanzadeh wrote: thank you, you gave me how to get fish instead of fish, it's very better. I'd suggest you make a diagram showing each file and indicate what files it imports by an arrow. If any arrows form a circle, you (may) have recursive imports. You should try to organize your code so you don't have any loops in the above diagram. In reasonable designs, you can do that by factoring out some of the code into new bubbles. But if you have too many bubbles already, that just makes it harder to keep track of. The recursion can sometimes be debugged more easily by eliminating the from xxx import * forms., which really hides what things you get. You'll only get those symbols already defined in the particular loop, (which is generaly the ones defined before its import statment) and you won't find out about the missing one till you try to use it later. It can sometimes be mitigated by using from xxx import y1, y2 where you explicitly define those things before the import statement. However, both of these require you to have the imports somewhere NOT at the top of the file. And that can cause other problems. Best is to avoid any loops in the diagram. -- DaveA -- https://mail.python.org/mailman/listinfo/python-list

Weird ttk behaviour
Hi all,
I've just started trying to learn how to use ttk, and I've discovered
something that I don't understand. I'm using Python 3.3.0 in Linux Mint
15. Suppose I create the following module:
# begin tkderp.py
import tkinter as tk
import tkinter.messagebox as _
from tkinter import ttk
from imp import reload
_root = tk.Tk()
_root.withdraw()
def f():
style = ttk.Style(_root)
style.theme_create('newtheme', parent = 'default')
tk.messagebox.showwarning('test', 'test')
style.theme_use('newtheme')
tk.messagebox.showwarning('test', 'test')
# end tkderp.py
The function f() is supposed to spawn two warning dialogs. AIUI, the
style.theme.use('newtheme') line shouldn't make any difference - it
would refresh any existing ttk widgets and alter the appearance of any
subsequently created ones if I had changed any of the new theme's
settings, but in the above context nothing it does should be discernible
to the user. If I try to call f() the first warning gets shown, but the

If I try reloading the module and calling the function again, this time
the first of the two warnings raises the exception. Since I don't really
understand how the ttk.Style class works, I can't say whether this
behaviour is expected or not. But here's what's weird. Suppose that I
comment out the last two lines in the definition of f(), like so:
# begin modified tkderp.py
import tkinter as tk
import tkinter.messagebox as _
from tkinter import ttk
from imp import reload
_root = tk.Tk()
_root.withdraw()
def f():
style = ttk.Style(_root)
style.theme_create('newtheme', parent = 'default')
tk.messagebox.showwarning('test', 'test')
#style.theme_use('newtheme')
#tk.messagebox.showwarning('test', 'test')
# end modified tkderp.py
Unsurprisingly, importing the module and calling f() displays a single
warning dialog and raises no exception. If I then uncomment those two
lines, reload the module and call f() again (by entering
tkderp.reload(tkderp).f()), the function works like it was supposed to
in the first place: two warnings, no exceptions. I can reload the module
as many times as I like and f() will continue to work without any problems.

The struct_time type does not include information about what timezone it is in. Uhm … Python 3.3 introduced the tm_gmtoff member of struct_time, which contains the offset to UTC.

Email was very open in the beginning of the internet. Before there were bad actors. Since that time, email has become the internet service most used for bad purposes, to deliver bad payloads, spoof people into visiting fake websites to induce them to give away private information, etc. So, the email services have gotten more particular about what they deem safe email in lots of different ways. If you want to do these various odd and misleading things to the emails you send out, you will have to understand how to 'beat the systems' that have been employed to stop that stuff. Having read your questions here for the last year(s) I don't believe this is an area in which you excel. You always want quick answers to questions that often show your complete lack basic understanding of the question domain. If you really want to plod along with this email spoofing, why not take a couple of weeks to read all about how email works on the internet, how email has been used to deliver viruses and spoofing schemes. After you understand that stuff well enough to show your competence in a forum where there are other email experts, as your questions there. As has been pointed out by several people here, your questions are not python language issues, they are issues relating to how email protocols work.

Let me start by saying that the above is not best practice for how to write functions, and I'll explain why later, but for now I'll just fix the problem with the calculation. You have List = [15, 6, 6, 7, 8, 9, 40] and then the mean function walks through each of the items 15, 6, 6, 7, ... counting how many times that item is found: for i in List: thecount = List.count(i) thesum = sum(List) So the first time, i gets the value 15, thecount calculates List.count(15) which is 1, thesum calculates sum(List) which is 91, and the end of the loop is reached. The second time around, i gets the value 6, then thecount calculates List.count(6) which is 2, thesum calculates sum(List) *again*, which is still 91, and the end of the loop is reached. Third time around, i gets the value 6 again, thecount again gets the value 2, thesum yet again sums up List which still hasn't changed, so yet again gets 91. And so on, and so on, until the last iteration, where i gets the value 40, thecount calculates List.count(40) which is 1, thesum re-calculates the sum yet again, still getting the exact same result 91, and finally the for-loop comes to an end. Now the final calculation occurs: themean = thesum/thecount which is 91/1 or just 91. What do you actually want? It's much simpler: you want to count the *total* number of items, 7, not by counting each item individually. The total number of items is given by the length of the list: len(List) returns 7. And you want to sum the list once, there's no need to sum it 7 times. So the first step is to get rid of the for-loop, just calculate thesum = sum(List) once, and thecount = len(List) once. Once you've done that, please write back with your new code, because I think there will be some more improvements to be made. -- Steven -- https://mail.python.org/mailman/listinfo/python-list

Well: - always include the output you get from your program, and say why you think it is incorrect - just style: we tend to name variables in lower case in Python, and classes with an upper case letter; List is a bit odd (but list is taken; how about values?) - more than style: WHY are you using global variables; just return the mean from the function! - teh variable List inside the function is _local_; your function does not accept a parameter - sum(List) sums the whole list you run it many times why? - what do you think count() does? - you should print i, thecount and thesum on each iteration of the list; it will help you see what your function is doing, and therefore to figure out what it is doing wrong I would write a mean like this: def mean(values): return sum(values) / len(values) There are circumstances where that is simplistic, but it is the classic definition of the mean.

You could manage your own SMTP connection. If only Python had some built in library that handled SMTP, that would be great!

[issue19030] inspect.getmembers and inspect.classify_class_attrs mishandle descriptors
Nick Coghlan added the comment: types is the OO equivalent to functools these days, in addition to its original role of exposing the internal type objects that aren't builtins. However, it seems to me that the fix for issue 1785 is simply *wrong*: it eliminated the exceptions at the expense of sometimes returning the *wrong answer*. The change in that issue means the inspect module isn't implementing the descriptor protocol correctly, and thus may provide a raw descriptor object when attempting to retrieve that attribute will return something else. Instead of the current behaviour, the inspect module should be trying getattr *first*, and only falling back to peeking in the __dict__ directly if that throws an exception. -- title: Make inspect.getmembers and inspect.classify_class_attrs Enum aware - inspect.getmembers and inspect.classify_class_attrs mishandle descriptors ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19030 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19034] More useful repr for Tcl_Obj
New submission from Serhiy Storchaka:
Currently the repr() for Tcl_Obj is not very useful. It exposes only Tcl type
name and Tcl object address.
import tkinter.ttk
tv = tkinter.ttk.Treeview()
tv.tag_configure('test', foreground='blue')
{}
str(tv.tag_configure('test', 'foreground'))
'blue'
tv.tag_configure('test', 'foreground')
color object at 0xb70f84b8
You need explicitly call str to get more useful information. This is awkward
when Tcl object hidden deeply in tuples or other data structure, or reported in
a backtrace. Actually every Tcl object can be represented as a string. I
propose to expose this representation in repr(). With proposed patch the output
of the last command will be: color object: 'blue'.

Well, this is a Lock here, not an ISO file. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19032 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue18050] embedded interpreter or virtualenv fails with ImportError: cannot import name MAXREPEAT
Serhiy Storchaka added the comment: Well. While the running different versions of binaries and Python files is not a good idea, perhaps we can apply this change. But only for 2.7 and 3.3. There is no need in this garbage in 3.4. I'm still not sure that there are no other inconsistencies between old static binaries and newer Python files. -- assignee: - serhiy.storchaka keywords: +patch stage: needs patch - patch review versions: -Python 3.4 Added file: http://bugs.python.org/file31794/sre_MAXREPEAT.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18050 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue18985] Improve the documentation in fcntl module
Vajrasky Kok added the comment: Updated patch based on Ezio's review. I reverted back the changes to Nul and module documentation (since it is not so clear whether we should categorize flock as Unix routine or not). -- Added file: http://bugs.python.org/file31795/fix_documentation_on_fcntl_module_v2.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18985 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue19035] tokenize.generate_tokens treat '\f' symbol as the end of file (when reading in unicode)
New submission from Alexey Umnov:
I execute the following code on the attached file 'text.txt':
import tokenize
import codecs
with open('text.txt', 'r') as f:
reader = codecs.getreader('utf-8')(f)
tokens = tokenize.generate_tokens(reader.readline)
The file 'text.txt' has the following structure: first line with some text,
then '\f' symbol (0x0c) on the second line and then some text on the last line.
The result is that the function 'generate_tokens' ignores everything after '\f'.
I've made some debugging and found out the following. If the file is read
without using codecs (in ascii-mode), there are considered to be 3 lines in the
file: 'text1\n', '\f\n', 'text2\n'. However in unicode-mode there are 4 lines:
'text1\n', '\f', '\n', 'text2\n'. I guess this is an intended behaviour since
2.7.x, but this causes a bug in tokenize module.
Consider the lines 317-329 in tokenize.py:
...
column = 0
while pos max: # measure leading whitespace
if line[pos] == ' ':
column += 1
elif line[pos] == '\t':
column = (column//tabsize + 1)*tabsize
elif line[pos] == '\f':
column = 0
else:
break
pos += 1
if pos == max:
break
...
The last 'break' corresponds to the main parsing loop and makes the parsing
stop. Thus the lines that consist of (' ', '\t', '\f') characters and don't end
with '\n' are treated as the end of file.

[issue19030] inspect.getmembers and inspect.classify_class_attrs mishandle descriptors
Ethan Furman added the comment: Switching the order to try getattr first is going to make getting the doc from the descriptor problematic -- we have no way of knowing if the descriptor doc goes with the object we got back from getattr. Current patch adds VirtualAttribute to types, and reworks inspect.classify_class_attrs, inspect.getmembers, and Enum to use that instead of _RouteClassAttributeToGetattr (which has been removed). Tests are still needed for the new VirtualAttribute. Not sure VirtualAttribute is the best name; other ideas: - InstanceProperty - AttributeProperty - HiddenClassProperty -- stage: - patch review Added file: http://bugs.python.org/file31797/issue19030.stoneleaf.02.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19030 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
