xlwings v0.2.3 released

[Felix Zumstein]

I am happy to announce the release of xlwings v0.2.3: 

Lot of bug fixes and new features like:
- Sheet.add(), Sheet.count(), Sheet.all(), Sheet(1).autofit()
- Range('A1').number_format(), Range((1,1)).get_address()

and more, see the Release Notes here: 
http://docs.xlwings.org/whatsnew.html 

About xlwings: 
xlwings is a BSD-licensed python library that makes it easy to call python from 
Excel and vice versa: 

Interact with Excel from python using a syntax that is close to VBA yet 
pythonic. 
Replace your VBA macros with python code and still pass around your workbooks 
as easily as before. 
xlwings fully supports NumPy arrays and Pandas DataFrames.

It works with Microsoft Excel on Windows and Mac.

2d color-bar map plot

[Dhananjay]

Dear all,
I am bit new to the python/pyplot.
This might be simple, but I guess I am missing something here.
I have data file as follows:

2.1576318858 -1.8651195165 4.2333428278
2.1681875208 -1.9229968780 4.1989176884

.
.
.
(total of 200 lines)

Columns 1,2,3 corresponds to x,y,z axis data points.
This is not a continuous data. I wish to make a plot as a 2D with 3rd
dimension (i.e z-axis data) as a color map with color bar on right hand
side.

As a beginner, I tried to follow tutorial with some modification as
follows:
http://matplotlib.org/examples/pylab_examples/tricontour_vs_griddata.html

# Read data from file:
fl1 = open('flooding-psiphi.dat','r').readlines()
xs = ys = zs = []
for line in fl1:
line = line.split()
xs.append(float(line[0]))
ys.append(float(line[1]))
zs.append(float(line[2]))

print xs[0], ys[0], zs[0]
xi = np.mgrid[-5.0:5.0:200j]
yi = np.mgrid[-5.0:5.0:200j]
zi = griddata((x, y), z, (xi, yi), method='cubic')
plt.subplot(221)

plt.contour(xi, yi, zi, 15, linewidths=0.5, colors='k')
plt.contourf(xi, yi, zi, 15, cmap=plt.cm.rainbow,
norm=plt.Normalize(vmax=abs(zi).max(), vmin=-abs(zi).max()))
plt.colorbar()  # draw colorbar
plt.plot(x, y, 'ko', ms=3)
plt.xlim(-5, 5)
plt.ylim(-5, 5)
plt.title('griddata and contour (%d points, %d grid points)' %
  (npts, ngridx*ngridy))
#print ('griddata and contour seconds: %f' % (time.clock() - start))
plt.gcf().set_size_inches(6, 6)
plt.show()


However, I failed and getting long error as follows:

precision problems (corrected unless 'Q0' or an error)
  2 flipped facets

The input to qhull appears to be less than 3 dimensional, or a
computation has overflowed.

Qhull could not construct a clearly convex simplex from points:
- p228(v3):   2.4   2.4   1.4
- p600(v2):   1.4   1.4   8.8
- p452(v1):   5.7   5.7 8
- p304(v0):  -3.1  -3.1   2.4

The center point is coplanar with a facet, or a vertex is coplanar
with a neighboring facet.  The maximum round off error for
computing distances is 1.2e-14.  The center point, facets and distances
to the center point are as follows:

center point1.5951.5955.173

facet p600 p452 p304 distance=0
facet p228 p452 p304 distance=0
facet p228 p600 p304 distance=0
facet p228 p600 p452 distance=0

These points either have a maximum or minimum x-coordinate, or
they maximize the determinant for k coordinates.  Trial points
are first selected from points that maximize a coordinate.

The min and max coordinates for each dimension are:
  0:-3.134 5.701  difference= 8.835
  1:-3.134 5.701  difference= 8.835
  2:  -2.118e-22 8.835  difference= 8.835

If the input should be full dimensional, you have several options that
may determine an initial simplex:
  - use 'QJ'  to joggle the input and make it full dimensional
  - use 'QbB' to scale the points to the unit cube
  - use 'QR0' to randomly rotate the input for different maximum points
  - use 'Qs'  to search all points for the initial simplex
  - use 'En'  to specify a maximum roundoff error less than 1.2e-14.
  - trace execution with 'T3' to see the determinant for each point.

If the input is lower dimensional:
  - use 'QJ' to joggle the input and make it full dimensional
  - use 'Qbk:0Bk:0' to delete coordinate k from the input.  You should
pick the coordinate with the least range.  The hull will have the
correct topology.
  - determine the flat containing the points, rotate the points
into a coordinate plane, and delete the other coordinates.
  - add one or more points to make the input full dimensional.

Convert Qstring to string in windows

[C@rlos]

I have been tryed to convert a Qstring text to string on python, in linux that 
work fine but in windows when qstring contine á,é,í,ó,ú the converted text is 
not correct, contine extranger characters, 
this qstring text is an url from qdialogtext. 

in linux i do for this way: 
pythonstringtext=qstringtext.text().toUtf8.data() 
and it return a python string correctly. 

i need some help plese...

Help in using grako for parsing

[varun7rs]

Hello, 
I am trying to parse a file which ahs the below content. I tried using the 
split function but that wasn't a good programming practice. I had to use it 
repeatedly to split the line and then read my data. I thought of doing it in a 
better way which is when I came across grako. But I have no idea whatsoever 
about the usage of grako in a script. It would be nice if any of you could help 
me understand the usage of grako. I need to extract the values beside the 
variables z, f and x. The numbers represent the request ID, virtualNode ID and 
physical nodeID for x and it varies a bit for f,

Thanks a lot

We know Python, but not necessarily any terminology you throw at us.

I didn't respond to your previous post because I had no idea what a .sol 
file is and what you're up to. As far as I can see no-one did. Now you make 
it even harder to help you by forcing us to look up grako to not (sic!) 
understand your question...

You give sample input below. Perhaps you'll get more/better feedback if you 
provide a sample of the output you need, too, together with a more elaborate

windows log to event viewer

[Arulnambi Nandagoban]

Hello, 

 

I am trying to run a tcp server as a windows service. 

The project also includes an application layer protocol somewhat like CoAP
and few soap calls to data base.

There is some moment the code enter into exception during a soap method
call. This exception is not viewed in

Windows event viewer. Should I specify somewhere to log these exception in
windows event viewer. Or, give me some suggestion how to log some

Critical message in windows log.

(total of 200 lines)

Columns 1,2,3 corresponds to x,y,z axis data points.
This is not a continuous data. I wish to make a plot as a 2D with 3rd
dimension (i.e z-axis data) as a color map with color bar on right hand side.

As a beginner, I tried to follow tutorial with some modification as follows:
http://matplotlib.org/examples/pylab_examples/tricontour_vs_griddata.html

[...]

Initially I've just got comments about the code in general, though they may 
help you find your issues.



# Read data from file:
fl1 = open('flooding-psiphi.dat','r').readlines()


This reads all the lines into memory, into the list fl1.
For 200 lines this is not a bit issue, but since you process them immediately 
you are usually better off reading the file progressively.



xs = ys = zs = []


This is actually a bug in your code. I would guess you've based it on other 
example code such as:


  x = y = z = 0

The problem is that both these assignment statements assign the _same_ object 
to all 3 variables. With an int or a str this isn't an issue because they are 
immutable; any further math or modification actually makes new objects.


However, you use:

  xs = ys = zs = []

This makes exactly _one_ list, and assigns it (binds it in Python terms) to 
all three names.


The result is that when you append to the list, you're appending to the same 
list every time. Effectively this means (1) that xs, ys and zs have the same 
values and (2) they're 3 times as long as they should be.


Do this:

  xs = []
  ys = []
  zs = []

That makes three separate lists.


for line in fl1:
    line = line.split()
    xs.append(float(line[0]))
    ys.append(float(line[1]))
    zs.append(float(line[2]))


Returning to the reading the file progressively thing, for a really big file 
(and as a matter of general practice) you're better off writing this like:


  for line in open('flooding-psiphi.dat','r'):
      line = line.split()
      xs.append(float(line[0]))
      ys.append(float(line[1]))
      zs.append(float(line[2]))

which only ever reads one line of text from the file at a time.

Start by fixing the:

  xs = ys = zs = []

assignment and see how the behaviour changes.

 Subject: Permissions on files installed by pip?
 
 I've been using the python-nltk package on Ubuntu, but I need ntlk
 3.0
 now.  I used 'sudo aptitude purge python-nltk' to get rid of my
 existing installation,  followed instructions on the nltk website
 [1]
 starting at step 4 (since I already have python-pip  python-numpy
 packages installed).
 
 $ sudo pip install -U
 
 I couldn't get it to work, until I realized that the permissions 
 ownership on /usr/local/lib/python2.7/dist-packages were 'drwx--S---
 root staff'.  A 'chmod -R a+rX' on that directory seems to have fixed
 it.  Is it normal for sudo pip install to set the permissions that
 way, or did I do something wrong?

On debian wheezy:

ls -al /usr/local/lib/python2.7/dist-packages  

drwxrwsr-x 5 root staff 4.0K Jun 30 15:16 ./

I'm not sure pip is responsible for this anyway, so my money goes on you did 
something wrong :)

non-gobject based dbus library?

[Tycho Andersen]

Hi all,

An application I maintain recently moved away from the gobject event
loop to the tulip/trollius/asyncio event loop. However, we were using
python-dbus, which internally uses the gobject event loop, as our main
event loop. This worked nicely when we were gobject based, but now
that we're not, I'm trying to find alternatives to python-dbus so that
we can re-implement the dbus-based functionality.

I tried gbulb: https://bitbucket.org/a_ba/gbulb but it seems mostly
abandoned, and I had to hack on it to even get our application to
boot, and some things didn't work correctly.

Does anyone have any ideas?

(Please keep me in CC, I'm not subscribed.)

Thanks!

Tycho

The line xs = ys = zs = [] is almost surely not what you want to do.
It results in xs, ys, and zs all being the same object.  Look:

 xs = ys = zs = []
 xs.append(1)
 print(ys)
[1]
 

Since your xs, ys, and zs are all identical, some unfortunate part
of the plotting package is trying in vain to find some thickness to
the thing it's plotting, but it can't, because all the points you've
given it lie on the x=y=z plane.  (It's sad that it tries so heroically
to give a detailed error message that turns out to be so obscure.)

So spend a few more characters:
xs = []
ys = []
zs = []

Then, on to the next problem.

Here's a sketch:

Open the source file using a csv.reader(); open the destination file using a 
csv.writer().

Use zip() and a for-loop to iterate over the new column and the rows in the 
source.

Insert the new field into the source row, e. g. row.insert(3, field)

Use writerow() to write the modified row.

Processing xml for output with cElementTree

[Joseph L. Casale]

I am unfortunately unable to use lxml for a project and must resort to base 
only libraries
to create several nested elements located directly under a root element. The 
caveat is the
incremental writing and flushing of the nested elements as they are created.

So assuming the structure is abctext/cdtext/d/b/a if I would 
like to
manually deconstruct this in order to write each element in order of 
appearance, is there
any built in facility for this?

The way I am currently doing is rather pathetic...

Re: [Tutor] Convert Qstring to string in windows

pythonstringtext is a byte string that has to be decoded as UTF-8.
Here's the 'mojibake' result when it gets decoded as UTF-16LE or
Windows codepages 850 and 1252:

 s = u'áéíóú'
 b = s.encode('utf-8')

 print b.decode('utf-16le')

The native character size in the Windows kernel is 2 bytes, so UTF-16
is the path of least resistance for in-memory strings used with GUI
controls and file/registry paths. UTF-8 is preferred for text data in

[issue22656] `help` ignores `__doc__` of descriptors

[Ram Rachum]

New submission from Ram Rachum:

The builtin `property` lets you specify a `doc` argument for your properties, 
which is great because then it shows up in `help`. So I figured that when I'm 
writing my own descriptor, I could set `__doc__` on it and have `help` use it. 
Not so, `help` ignores it. 

See this example:

class Property(object):
Emulate PyProperty_Type() in Objects/descrobject.c

def __init__(self, fget=None, fset=None, fdel=None, doc=None):
self.fget = fget
self.fset = fset
self.fdel = fdel
if doc is None and fget is not None:
doc = fget.__doc__
self.__doc__ = doc

def __get__(self, obj, objtype=None):
if obj is None:
return self
if self.fget is None:
raise AttributeError(unreadable attribute)
return self.fget(obj)

def __set__(self, obj, value):
if self.fset is None:
raise AttributeError(can't set attribute)
self.fset(obj, value)

def __delete__(self, obj):
if self.fdel is None:
raise AttributeError(can't delete attribute)
self.fdel(obj)

def getter(self, fget):
return type(self)(fget, self.fset, self.fdel, self.__doc__)

def setter(self, fset):
return type(self)(self.fget, fset, self.fdel, self.__doc__)

def deleter(self, fdel):
return type(self)(self.fget, self.fset, fdel, self.__doc__)


class A:
x = property(lambda self: 3,
 doc='Helpful text')

y = Property(lambda self: 7,
 doc='More Helpful text')


help(A.x) # Shows 'Helpful text'
help(A.y) # Does not show 'More Helpful text'


It seems that `property` is special-cased or something. I want to be able to 
set a docstring on my own descriptors.

[issue22656] `help` ignores `__doc__` of descriptors

[R. David Murray]

R. David Murray added the comment:

You might find issue 5890 to be interesting reading.  It's been long enough 
that I forget the details, but I think the short answer is yes, property is 
special cased.   So probably what you want to do is subclass property.

Given the knock-on issue that fix caused, I've always been a little bit 
uncomfortable with it.  Perhaps you will see a way to generalize things.

[issue22658] IMAP4 Example lacking host information

[James Goodwin]

New submission from James Goodwin:

The IMAP4 Example for Python 3.4 (Section 21.15.2) does not show the 
appropriate host information for the example to work.  

Suggested fix would be to change the line M = imaplib.IMAP4() to M = 
imaplib.IMAP4('localhost')  This will bring the example inline with the poplib 
example (Section 21.14.2).

[issue18216] gettext doesn't check MO versions

[Antoine Pitrou]

Antoine Pitrou added the comment:

The linked docs say: an unexpected minor revision number means that the file 
can be read but will not reveal its full contents, when parsed by a program 
that supports only smaller minor revision numbers.

Unless there an important piece of contents that can be missed, I would say a 
warning is more of a distraction here.

[issue22661] WinXP concerns

[Tcll]

New submission from Tcll:

About a week ago I read you were also dropping support for WinXP.

This will cause issues for me as I don't support newer Win (or should I say 
MS-RAT infested) OS's

I use linux now, but I still use XP as a testing interface for Windows.
(I will not install any newer windows as I prefer my freedom when MS pushes 
their button)

I hope this changes development aims to continue supporting WinXP...

if not, I can no longer consider python as cross-platform,
and will be forced to use an outdated cross-platform interpreter.


I'm still looking into how to disable the MS-RAT with python, as a friend of my 
friend has already done it.
my friend wasn't interested in asking him how when he did it, and getting in 
contact with him is quite difficult.

if (and only if) I can disable MS's RAT, I will gladly use a newer windows as a 
testing interface, so long as I can hack it like XP.
(I like doing cool things to my OS, which is what I mean by hacking)

The reason I chose 2.7 for the python version is due to me being a PyOpenGL 
programmer and that the extension runs faster in 2.7

This is not an appropriate discussion for the bug tracker.  python-dev would be

That said, we won't be dropping support for XP in 2.7, since it is in

Yeah, it wasn't so much negative, as...edgy? :)

We can't really support what Microsoft doesn't support, since we use the 
Microsoft compilers.  There is discussion about better support for alternate 
compilers, though, and if that eventuates *some* sort of support for XP ought 
to be possible, though exactly what it would look like would be up to the 
people interested enough to do it.

[issue22662] subprocess.Popen.communicate causing local tty terminal settings to change inconsistently

[Kyle]

New submission from Kyle:

I'm not sure if this is a bash or Python issue.  I'm trying to run a command on 
a remote server, using the subprocess module.  I call ssh inside of 
subprocess.Popen(...).communicate(), like so:

output = subprocess.Popen([/bin/env %s /usr/bin/ssh -ttt %s@%s -- %s; % (env, 
user, host, command)], stdout=subprocess.PIPE, stderr=subprocess.PIPE, 
shell=True).communicate()

Following the call to communicate(), my terminal settings are changed.  
However, it's not always repeatable.  Sometimes it happens, and other times it 
does not.  When it does happen, I've noticed that the following tty options are 
ON prior to the command executing, and OFF afterwards (output from stty -a):
icrnl opost isig icanon echo echoe echok

Something with the communicate() call seems to cause the issue.  I don't 
actually have to print anything to the screen from Python for it to occur.

The problem goes away if I remove the -t option to ssh, however, I'm passing 
through the TERM environmental variable, and need -t to be set.  Because of 
this, I'm not sure if the problem is with the Python call, or something within 
Bash.

I've been able to repeat this on Ubuntu 13.10 running Python 2.7.5, and on Red 
Hat 6.4 running Python 2.6.6.

[issue22661] WinXP concerns

[Tcll]

Tcll added the comment:

ah I see
in that case, I work on my program for you guys as well :)

it won't be finished any time soon, but what I'm working on is a recompiler 
specifically for this garbage of cross-platform support being hindered.

so in the mean-time try to do what you can towards keeping XP supported ;)

just understand, from what I've been hacking and paying attention to, MS wants 
to control both the market and Windows PC users.
(the initial release if the XBox One is my biggest push away from Windows)
^ MS is only holding back on those restrictions for a later time

that RAT I talk about has been found in all versions of Windows from Vista and 
up.
(it's not confirmed by hackers to work in Vista, but that doesn't mean it 
doesn't work)

I wish you guys the best of luck ;)
Thanks for trying at least :)

+1 guys ;)

*looks toward other developers*
finally, developers that do stuff right

[issue22656] `help` ignores `__doc__` of descriptors

[Ethan Furman]

Ethan Furman added the comment:

Yeah, that was interesting. ;)

I think there are two different, yet related, issues:

  - which __doc__ should help display?

  - how should __doc__ be inherited?

The issue we should deal with here is the first, as what help displays does not 
have to follow the exact same rules as inheritence and magic-method lookup; 
specifically, help should be free to look for a __doc__ on the instance and 
incorporate it.

[issue22664] IDLE: Standard output and error from multiprocessing vanishes

[ppperry]

New submission from ppperry:

Note: not sure whether this issue belongs as a behavior or an enhancement

In IDLE:
 def print_a_test_string():
 print test

print_a_test_string()
test
threading.Thread(target=print_a_test_string).start()
test
multiprocessing.Process(target=print_a_test_string).start()
[test is not said]

Running this example in the standard interpreter will print test all three 
times (in current thread, new thread, new process). (Acutally, I got an 
AttributeError and had to work aroung it using functools.partial(print, test))

[R. David Murray]

R. David Murray added the comment:

Thanks for the patch, Vajrasky, but I chose a different fix, since the proposed 
one could leave the file open if the shlex constructor raised an error.  Not 
particularly important, but as long as we are cleaning up the code we might as 
well make it as clean as we can.

Since 2.7 doesn't generate ResourceWarnings I chose not to apply it there.

[issue16079] list duplicate test names with patchcheck

Robert Collins added the comment:

FWIW testtools rejects test suites with duplicate test ids; I'm considering 
adding that feature into unittest itself. We'd need an option to make it warn 
rather than error I think, but if we did that we wouldn't need a separate 
script at all.

[issue22606] Inconsistency between Python 2 and PyPy regarding future imports

[Terry J. Reedy]

Terry J. Reedy added the comment:

A difference in internal behavior between CPython and PyPy is not necessarily a 
CPython bug, or even a PyPy bug.  It may just be an implementation choice.  So 
ignore PyPy and consider Python doc versus CPython behavior.

Running the three quoted lines by themselves gives SyntaxError.  compiling the 
ast object does the same.  So this is one of those SyntaxErrors not noticed (or 
at least not enforced) until the compile phase. This was specified in PEP 236 
and still is in the Reference: A future statement is recognized and treated 
specially at compile time.  Whenever the compiler raises SyntaxError, it 
declares the AST to be syntactically invalid.  How can this be?

The ast doc starts with The ast module helps Python applications to process 
trees of the Python *abstract syntax grammar*. ... this module helps to find 
out programmatically what the current grammar looks like. (asterisks added). 
The abstract grammar does *not* include a 'Future' statement. In your code, 
x.body[1] is an ImportFrom object.  So the ast from the code above does not 
violate the abstract grammar and there is no parsing bug.

We should either either close this as 'not a bug' or change to a doc issue to 
add something about the ast abstract grammar being 'looser' than the defacto 
context-sensitive Python grammar.  Perhaps something like The language defined 
by the context-free LL(1) abstract grammer is a superset of the actual 
context-sensitive Python language. (Consider position-dependent future 
statements.)  Consequently, some ast trees generate a SyntaxError when 
compiled.

It is somewhat arbitrary when a print statement is converted to a print 
expression -- while parsing, or while compiling.  The two implementations made 
different choices.

Since the parser does recognize a Future statement and change the ast objects 
it creates, it would be possible to add a Future object to ast trees.  But it 
would do no good as far as the syntax check goes.  The context-free LL(1) 
parser could not recognize a violation of the context-sensitive constraint.

[issue22607] find by dichotomy the failing test

[Terry J. Reedy]

Terry J. Reedy added the comment:

I believe the goal, and a better title, is Automate leak discovery within a 
group of tests.  Bisection or dichotomy is a means, not a goal, and should not 
be part of the title.

Leak discovery means 'find a test within the group that has a leak (which we 
know or suspect might be occurring)'. 

'Test' can mean multiple modules, one module, one TestCase class, one test_xxx 
method, one subtest, or one assert.  What might it mean in 'group of tests'?  
Pinning a leak on a particular statement likely has to be done manually; 
eliminate that.  On the other hand, it is feasible (see below) to automatically 
blame a particular test method and perhaps a particular subtest.  So interprete 
'tests' as 'test methods or subtests'.

Unittest can run all test methods in a module, all test methods in a test 
class, or an individual test method.  Idle already has a module browser (Class 
Browser), based on stdlib's pyclbr and Idle's TreeWidget, that could be adapted 
(perhaps using ttk.Treeview instead) to produce a module-test_class-test tree.  
Add buttons to select a particular leak test and others to select manual or 
auto nagivation of the tree and we might have something worthwhile.  It could 
go in Tools/Scripts or PyPI.

I have not used subtests yet since they are not available on 2.7, but I can 
imagine semi-automated editing, saving to a temp file, and running.  I would 
need experience with real subtest bisection to comment on the patch.
