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')
ꇃ꧃귃돃뫃
>>> print b.decode('850')
├í├®├¡├│├║
>>> print b.decode('1252')
áéÃóú
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
files and network communication.

The caveat is the incremental writing and flushing of the nested elements as they are created.

non-gobject based dbus library?
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 -- https://mail.python.org/mailman/listinfo/python-list

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.
Cheers,
Cameron Simpson

This might be simple, but I guess I am missing something here.
I have data file as follows:
2.1576318858 -1.8651195165 4.2333428278

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:

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
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... .C@rlos III Escuela Internacional de Invierno en la UCI del 17 al 28 de febrero del 2014.
