Re: list comparison vs integer comparison, which is more efficient?

You can test them with the timeit module, but my personal suspicion is
that any difference between them will be utterly and completely
dwarfed by all your sqrt(2) calls in the complex constructors. If you
break those out, and use a tuple instead of a list, you could write
this very simply and tidily:
bits = {
(0,0): complex(1/math.sqrt(2),1/math.sqrt(2)),
(0,1): complex(1/math.sqrt(2),-1/math.sqrt(2)),
(1,0): complex(-1/math.sqrt(2),1/math.sqrt(2)),
(1,1): complex(-1/math.sqrt(2),-1/math.sqrt(2)),
}
# QPSK - TS 36.211 V12.2.0, section 7.1.2, Table 7.1.2-1
def mp_qpsk(self):
r = []
for i in range(self.nbits/2):
bit_pair = self.sbits[i*2:i*2+2]
r.append(bits[tuple(bit_pair)])
return r
At this point, your loop looks very much like a list comprehension in
full form, so you can make a simple conversion:
# From itertools recipes
# https://docs.python.org/3/library/itertools.html
def pairwise(iterable):
s - (s0,s1), (s1,s2), (s2, s3), ...
a, b = tee(iterable)
next(b, None)
return zip(a, b)
# Replace zip() with izip() for the Python 2 equivalent.
def mp_qpsk(self):
return [bits[pair] for pair in pairwise(self.sbits)]
How's that look? I don't care if it's faster or not, I prefer this form :)

I think it is.
http://www.tcl.tk/man/tcl8.6/TkCmd/text.htm#M41 does not mention a way to
configure the set of word chars either:
?submodifier? wordstart
Adjust the index to refer to the first character of the word containing the
current index. A word consists of any number of adjacent characters that are
letters, digits, or underscores, or a single character that is not one of
these. If the display submodifier is given, this only examines non-elided
characters, otherwise all characters (elided or not) are examined.

I think you just want some string formatting so (untested) either

I’d appreciate any help you can provide. I’m having problems passing
command line parameters from Windows 7 into a Python script (using
Python 3.4.2). It works correctly when I call the interpreter
explicitly from the Windows command prompt, but it doesn’t work when I
enter the script name without calling the Python interpreter.
This works:
python myScript.py arg1 arg2 arg3
This doesn’t work:
myScript.py arg1 arg2 arg3
The Windows PATH environment variable contains the path to Python, as
well as the path to the Script directory. The PATHEXT environment
variable contains the Python extension (.py).
There are other anomalies too between the two methods of invoking the
script depending on whether I include the extension (.py) along with the
script name. For now I’m only interested in passing the arguments
without explicitly calling the Python interpreter.
Here is the script:
#! python
import sys
def getargs():
sys.stdout.write(\nHello from Python %s\n\n % (sys.version,))
print ('Number of arguments =', len(sys.argv))
print ('Argument List =', str(sys.argv))
if __name__ == '__main__':
getargs()
Result_1 (working correctly):

Number of arguments = 1
Argument List = ['C:\\Python34\\Scripts\\myScript.py']
As a beginner I’m probably making a mistake somewhere but I can’t find
it. I don’t think the shebang does anything in Windows but I’ve tried
several variations without success. I’ve tried writing the script using
only commands, without the accouterments of a full program (without the
def statement and without the if __name__ == ‘__main__’ …) to no avail.
I’m out of ideas. Any suggestions?

The data strings for a lot of different command keys in the registry were missing the %* (percent star) characters. Thanks Chris for the explanation on why the %* string is needed. Here is a sample key: S1-5-21-1560217580-722697556-320042093-1000-Classes py_auto_file shell open command The corrected data for the key looks like this: C:\Python34\python.exe %1 %* I used the 'find' tool in regedit to search for python in the registry. There were many hits on the word python but only a handful had data fields similar to the one above. Every instance was missing the %* string. I modified them all. My script didn't start working until after I'd modified the very last one. Happily, my computer still boots after mucking around in the registry.

Re: Python Tk Tix GUI documentation builder overview and tips
Hi, I have had issues running Tix on python 2.7.6 and 3.4.2: More details on the issue here. http://stackoverflow.com/questions/27751923/tix-widgets-installation-issue Has anyone had similar issues with Tix? Thanks and Happy New Year. On Friday, March 27, 2009 5:19:42 PM UTC-4, bal...@googlemail.com wrote: I have recently started development for a small video conversion project using a GUI. After some research I decided to use Tkinter/Tix (Tk/Tix). The reasons are mainly: 1. the GUI is rather simple, and 2. the end-user is not necessarily technically inclined so I want to keep a) required libraries as few as possible, and b) installation as painless as possible. 3. Tk/Tix is included with Python. Thus only a Python installation is needed. Nothing else. 4. Tk itsself misses some rudimentary widgets like meters, multi/colum lists, grid and scrolled widgets. Tix provides those. Good enough for my little application (more advanced and more modern widgets are available in frameworks like Qt, Gtk, or wxWindows). Before starting I spent some effort to find a) relevant documentation, b) GUI Builders which might help me, c) answers to non-obvious questions. The process took some time and effort so I want to share my findings: a) Documentation resources Python Docs http://docs.python.org/library/tkinter.html Tk Commands http://www.tcl.tk/man/tcl8.5/TkCmd/contents.htm Tix Reference http://tix.sourceforge.net/man/html/contents.htm Tix demo application You want to extract the Tix demo application coming with the Tix 8.4.3 source distribution. It containsexamples for many widgets - unfortunately none for multi-column HList or the Grid (see below). https://sourceforge.net/project/showfiles.php?group_id=5649package_id=5704 Tix8.4.3-src.tar.gz, then look in /Tix8.4.3/Python/Demo/tix Thinking in Tkinter I recommend the Individual programs online http://www.ferg.org/thinking_in_tkinter/index.html b) GUI development tools ActiveState GUI Builder (using grid layout) SpecTcl is the predecessor of GUI Builder (by ActivaState). http://spectcl.sourceforge.net/ FAQ (where to get source) http://aspn.activestate.com/ASPN/Mail/Message/komodo-announce/3355346 PAGE v3.0 by Stewart Allen (using placer layout) http://page.sourceforge.net/ There are many more for other GUI toolkits mentioned in this post: http://mail.python.org/pipermail/python-list/2004-February/250727.html Finally I decided to use the packer layout and create the widgets manually. Just the simplest and quickest way for me. c) How do I ...? How do I use all methods available in the Tix Grid? Tix Grid with full implementation of all methods http://klappnase.bubble.org/TixGrid/index.html How do I create a multi-column Tix.HList? import Tkinter as Tk import Tix root = Tix.Tk() # setup HList hl = Tix.HList(root, columns = 5, header = True) hl.header_create(0, text = File) hl.header_create(1, text = Date) hl.header_create(1, text = Size) # create a multi-column row hl.add(row1, text = filename.txt) hl.item_create(entry_path, 1, text = 2009-03-26 21:07:03) hl.item_create(entry_path, 2, text = 200MiB) I haven't found out how to right-justify individual columns? Anyone? How to implement Tk GUI with multiple threads? Usually there are two options to make threads wait for an event: * gui thread polling (lame) see here how to use Tk.after() (actually a Tcl command) to poll http://uucode.com/texts/pylongopgui/pyguiapp.html see here how to imitate the Tk event loop to poll for non-Tk events (a socket, for example) https://sourceforge.net/project/showfiles.php?group_id=5649package_id=5704 Tix8.4.3-src.tar.gz, then look in /Tix8.4.3/Python/Demo/tix/ tixwidgets.py, find loop() * multithreaded with events (the option to choose) Basically this uses bind and event_generate to send Notify messages to the Tk instance. I suspect the following example failed due to not synchronising the event_generate call http://coding.derkeiler.com/Archive/Python/comp.lang.python/2006-07/msg01479.html For multithreading Python Tk GUI applications the following rules apply: 1. same thread calling Tk must do all subsequent GUI calls, 2. other threads may send events with send_event to the root Tk instance, 3. with threading problems you might try to synchonise access to event_generate(). Using event_generate() with one non-GUI thread seems to be safe. -- https://mail.python.org/mailman/listinfo/python-list

The surprise is really that the 3rd test is True not that the fourth is
False.
First, as should be expected, a byte string is a sequence of (small)
ints. So b'b' is a (short) byte string and the set set(b'abc') is
composed of three ints. You should not expect your inclusion test to
return True when testing for a bytes-type object in a set of int-type
objects. And that explains your False result in the 4th test.
type(b'abc')
class 'bytes'
type(b'abc'[0])
class 'int'
But things are different for strings. You might think a string is a
sequence of characters, but Python does not have a character type. In
fact the elements of a string are just 1 char long strings:
type('abc')
class 'str'
type('abc'[0])
class 'str'
You would not logically expect to find a string 'b' in a set of
characters in, say C++, where the two types are different. But that's
not the Python way. In Python a set of characters set('abc') is really
a set of (short) strings, and the character 'b' is really a (short)
string, so the inclusion test works.
Python's way of returning a 1-byte string when indexing a string
(instead of returning an element of type character) allows this
surprising result.
'abc'[0]
'a'
'abc'[0][0]
'a'
'abc'[0][0][0]
'a'
'abc'[0][0][0][0]
'a'
...
I've never considered this a problem, but a infinitely indexable object
*is* a bit of an oddity.

Put float number in message.
Here is my last line in a simple program that is a scribus script.
end = scribus.messageBox('Book Spine Width', 'dummy', ICON_WARNING, BUTTON_OK)
This works. Now I want to put a float number called S instead of 'dummy'.
If I just put S in the command I get an error. If I convert S to a string with
SS = str(S)
first and then
and substitute SS for 'dummy' I get what appears to be the ASCII numbers
representing the characters, not the characters I want.
I am a total newbie with Python. Anyone have a suggestion? Can I use a print
command instead?

[issue23116] Python Tutorial 4.7.1: Improve ask_ok() to cover more input values
Carol Willing added the comment: @amylou Thank you for submitting this documentation suggestion about the Python Tutorial. This tutorial section, 4.7.1 Default Argument Values, tries to show that a function can have multiple input arguments which may be given default values. While the suggestion to use lower() does offer more robust input handling, it also adds some complexity to the example by introducing another function to a possibly new user. I do believe that the 'ask_ok' function could be improved by renaming the 'complaint' argument to something more positive, perhaps 'reminder'. I would also recommend replacing the error message 'uncooperative user' to something with a softer tone, perhaps 'invalid user response'. @amyluo If you are interested in working on documentation, section 6 of the Developer Guide is a handy resource (https://docs.python.org/devguide/docquality.html). -- assignee: - docs@python components: +Documentation nosy: +docs@python, willingc ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23116 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23153] Clarify Boolean Clause Results
R. David Murray added the comment: I mistyped 'josh' as 'joel', sorry. Ethan covers it pretty well, but I'll add a few things. Boolean operators are indeed not always used in a boolean context. There is a long tradition in Python of using them to return values via the short-circuit mechanism. Python is not the only language that does this. That said, there are disadvantages to that use of boolean operators, and eventually the trinary expression 'x if y else z' was introduced, and is now the preferred way to compute such values. The tutorial has not been updated to reflect that, and that is something that could be done, but probably requires a significant rewrite...someone on irc pointed out that the passage we are discussing is the first introduction of 'or' in the tutorial). However, the short-circuit-and-value-returning behavior of the boolean operators will not change, since it is a long standing part of the language. Your suggestion that this whole thing be discussed more is a valid point, but the question is, is this point in the tutorial the place to do it? Again, a more extensive rewrite is probably needed in order to make a real improvement (a project that is being discussed, whose status I don't know). Finally, the 4.1 text you quote is noting and/or as an exception is talking about the built-in functions and operators. and and or are important exceptions both because their default is different from other logical operations and because, unlike the other python operators, a type cannot override them. Thus they always return a value, whereas other *logical* operations will return a boolean *unless otherwise documented* in the documentation for the type. (I'm not sure there are any exceptions to that in the sdtlib, but there are, for example, in numpy.) Now, that all said, the tutorial section explicitly mentions the behavior of and and or, so I don't see how their being exceptional in this regard is an issue with the tutorial text. If you assigned another logical expression to a variable, you'd get True or False, but in Python's philosophy that's just a special case of the fact that all values in python have a truth value, as discussed by Ethan. So, in summary, I hear you that as an experienced programmer this tutorial section did not give you all the information you wanted. However, it is a *tutorial*, and so it *can't* (and be a readable *tutorial*) cover all the issues. Perhaps it could cover more if it were rewritten, but I don't think changing this section in any of the ways suggested so far would, as it is currently organized, be an improvement. If anyone wants to take another stab at it, though, we'll definitely evaluate it. willingc on IRC suggested adding links to other parts of the docs, for further reading, and that might be worthwhile if someone wants to take a look at making a suggestion in that regard. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23153 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue23156] Update tix install information in tkinter tix chapter of doc
New submission from Terry J. Reedy: Update tix install info in doc. Using tix starts with 3 lines for testing one's tix install and continues '''If this fails, you have a Tk installation problem which must be resolved before proceeding. Use the environment variable TIX_LIBRARY to point to the installed Tix library directory, and make sure you have the dynamic object library (tix8183.dll or libtix8183.so) in the same directory that contains your Tk dynamic object library (tk8183.dll or libtk8183.so). The directory with the dynamic object library should also have a file called pkgIndex.tcl (case sensitive), which contains the line: package ifneeded Tix 8.1 [list load [file join $dir tix8183.dll] Tix]''' Almost nothing above matches my working-with-tix 3.4.2 Win 7 install. I do have a tix library directory: python34/tcl/tix8.4.3, but the version number is much newer. Since it is in the right place, TIX_LIBRARY is not needed and there is none. python34/DLLs contains tcl86t.dll and tk86t.dll and NO tix.dll. Is the once separate tix dll now part of tk dll? I cannot find pkgIndex.tcl; it is certainly not in the DLLs directory nor in the /tcl. The current doc seems useless to people who do not have tix working.

To show how to return a Boolean result from a Boolean clause. If there's a better way, I'm all for it. 2. Most is a generalization. Perhaps Many is a better term? All traditional 3GLs and some other scripting languages don't; e.g. REXX and Beanshell return Boolean. But it's not important here. 3. As I said, or some better method. I've been programming 30 years but am only now learning Python. All I asking for is better clarification in the tutorial. If this were a wiki I would add one myself. Re: Ethan; quote from the line above, same section in the Tutorial: When used as a general value and not as a Boolean, the return value of a short-circuit operator is the last evaluated argument. If this isn't correct, please fix it. And this whole sentence is a bit weird to me - Boolean operators are *always* used in a Boolean context - unless the op is overloaded with some other functionality. Why would it return anything else? (well let's not go there...) Re: R.David Sorry I didn't see any input from Joel. But, yes, this is a tutorial. I argue that using A = (B or C or D) construct is not good, intuitive programming style, anyway. To me this looks like A should hold a Boolean, even only from a pseduocode standpoint. Even so, one wouldn't need to cast a Boolean if a Boolean was returned, as old programmers like me would expect. But, OK, so don't use bool() - but what you said is basically what I'm looking for IN the tutorial - eduction about why a Boolean should NOT be expected. Or how to achieve a Boolean, since it's a valid data type since version 2.3. This is a tutorial, after all. For example, the full documentation for v3.4 section 4.1: Operations and built-in functions that have a Boolean result always return 0 or False for false and 1 or True for true, unless otherwise stated. (Important exception: the Boolean operations or and and always return one of their operands.).

This is a tutorial, and part of the zen of Python is that all expressions have a boolean value.

[issue23153] Clarify Boolean Clause Results
Ethan Furman added the comment:
Apologies, my wording was poor -- the last item evaluated is the one returned,
but all items may not be evaluated. As soon as the answer is known Python
stops evaluating any remaining items.
So in the example:
-- string1, string2, string3 = '', 'Trondheim', 'Hammer Dance'
-- string1 or string2 or string3
'Trondheim'
string2 is returned because it satifies the `or` conditions, and string3 is not
evaluated.
Re: John
I appreciate you have many years of programming experience, but there are going
to be differences between what is good practice in those languages and what is
good practice in Python. IMO, the big three differences are:
- white space indentation
- everything is an object (variables, functions, classes, instances,
any piece of data...)
- everything has a truthy of falsey value -- e.g.
-- string1, string2, string3 = '', 'Trondheim', 'Hammer Dance'
-- if string2:
...print('string2 has a value! It is %s' % string2)
...
'string2 has a value! It is Trondheim'
notice there is no `if bool(string2)` or `if string2 == False` (which would
be False).
As far as finding that bit of the tutorial confusing, there is no way to have a
single document that is crystal clear to everyone who reads it. This section
is correct, as is section 4.1 -- `or` is being used, so the operand is
returned, not True or False.

[issue1284316] Win32: Security problem with default installation directory
Steve Dower added the comment: I'll reassign this to me, as I'm looking into making Program Files the default location for 3.5. I'd like to release at least some of the alphas with the change active by default (i.e. it's easy to select the old directory) to get broader feedback. So far I haven't encountered any trouble other than in pip (as is being discussed at https://github.com/pypa/pip/issues/1668). If things don't work well in the early releases of 3.5 we can easily revert the change, though I suspect the main feedback is going to be about the amount of typing required. In that case, I'll look into hardening the permissions on the root directory as part of installation. Unless some really bad scenarios arise, getting the legacy permissions will be opt-in. As 3.5 will be the first version with that change there shouldn't be any direct back-compat issues - we can't make a change like that in maintenance releases or even 3.4. -- assignee: loewis - steve.dower versions: -Python 2.7, Python 3.2, Python 3.3, Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1284316 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23132] Faster total_ordering
Raymond Hettinger added the comment:
Thanks Serhiy. I really like this clean-up. When there is an exception in the
user's root comparison operation, the traceback is more intelligible now.
If you're interested, here are two additional optimizations:
_op_or_eq = '''
op_result = self.%s(other)
# Since bool(NotImplemented) is true, the usual special case test isn't
needed here
return op_result or self == other
'''
# setting NotImplemented as a local constant saves one or two global lookups
per call
exec('def %s(self, other, NotImplemented=NotImplemented):%s' % (opname, opfunc
% root), namespace)

[issue22382] sqlite3 connection built from apsw connection should raise IntegrityError, not DatabaseError
Gerhard Häring added the comment: Reusing the apsw connection in the sqlite3 module was deprecated a long time ago. It is simply not supported, even if there is still code left in the module that supports this somewhat. This code should then be removed.

[issue23132] Faster total_ordering
Raymond Hettinger added the comment: Serhiy, this is a really nice idea. By removing the additional layer of indirection, the code is more intelligible, runs faster, and the tracebacks make more sense when the user's root comparison raises an exception. Since there are only twelve functions involved, I don't think the function templates give us much of a payoff. Instead, it would be better to just precompute the 12 functions rather than have 5 templates. I've attached a patch relative to Python 3.4. Ideally, I would like this backported to 3.4 to fix the regression in performance and intelligibility. One further possible change is to localize the NotImplemented global variable. This will reduce the overhead of NotImplemented checking to almost nothing and almost completely restore the performance of earlier versions. -- Added file: http://bugs.python.org/file37591/total_ordering.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23132 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue22231] httplib: unicode url will cause an ascii codec error when combined with a utf-8 string header
Bob Chen added the comment: Is there any possibility that we encapsulate urllib.quote into httplib? Because many developers wouldn't know about this utility function.

[issue22231] httplib: unicode url will cause an ascii codec error when combined with a utf-8 string header
Demian Brecht added the comment: utf-8 encoding is only one step in IRI encoding. Correct IRI encoding is non trivial and doesn't fall into the support policy for 2.7 (bug/security fixes). I think that the best that can be done for 2.7 is to enhance the documentation around HTTPConnection.__init__ (unicode hostnames should be IDNA-encoded with the built-in IDNA encoder) and HTTPConnection.request/putrequest noting that unicode paths should be IRI encoded, with a link to RFC 3987. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22231 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
