Re: How to test for type or instance of dict_values?
Very late to the party, but I just encountered a very similar problem and found
a solution:
```
import collections
obj = {"foo": "bar"}
isinstance(obj.values(), collections.abc.ValuesView) # => True

Hope that helps someone out there :)

extending class static members and inheritance
Hi All,
I have a question.
Let says I have the following two classes:
class Base(object):
__mylist__ = ["value1", "value2"]
def somemethod(self):
pass
class Derived(Base):
__mylist__ = ["value3", "value4"]
def anothermethod(self):
pass
what I would like to accomplish is that the class Derived has the member
__mylist__ extended or merged as ["value1", "value2", "value3", "value4"].
Is there anyway I could accomplish this?
I was thinking on accomplishing this as follows:
class Derived(Base):
__mylist__ = Base.__mylist__ + ["value3", "value4"]
def anothermethod(self):
pass
Is there a better way? Perhaps a decorator?
Thanks in advance and regards,
Fabian

Different cache filename
Hi, when load a module "mymodule.py" with importlib.machinery.SourceFileLoader a bytecode file is created as mymodule.cpython-33.pyc. If I load a module "mymodule.ext.py" the same way the same bytecode file is created as mymodule.cpython-33.pyc.

getsockopt
Hello,
my name is fabian and i'm a student from northern germany. right now i
try to create som kind of decapsulation of esp-udp packets using python.
therefor i need to use the socket.getsockopt (SOL_IP, IP_OPTIONS, 20)
method. But al i get is some empty value. Nothin.
Does someone know or have an working exmaple of how to use this method??
The lines:
s = socket(AF_INET, SOCK_DGRAM, IPPROTO_IP)
s.bind(('',4500))
while 1:# Run until cancelled
message, client = s.recvfrom(1400) # <=256 byte datagram
hdr = s.getsockopt (SOL_IP, IP_OPTIONS, 20)
print "Client connected:", client
print "HDR:" + binascii.hexlify(hdr)

If you want to test this, be rot and try
echo asd | nc -u 127.0.0.1 4500
to create some packets ...
This should do it.

Hey,
you are right - i just re-read the ip (7) man - i only get the ip options ..
but do you know a way of getting the whole header?
'cause what i'm trying to do is, to "remove" the udp-header of the packet i
recieved and sendind a new packet without the udp-header.
I want to do this by taking it's payload (incl. esp-hdr) and ip-header and
resending it to my system creating a new packet with the old ip-header and
payload (incl. esp-hdr) i got from the recvd packet.
Before:
++-+--+--- - -
| IP HDR | UDP HDR | ESP HDR | PAYLOAD ...
++-+--+--- - -
After :
++-+--- - -
| IP HDR | ESP HDR | PAYLOAD ...
++-+--- - -

Well actually I managed to recieve the encapsulated esp packages,
decapsulate them and send them to my system using
sr = socket(AF_INET, SOCK_RAW, IPPROTO_ESP)
...
sr.sendto(message (MY_IP,0))
it does work and my system correctly deciphers the packages (i get an icmo
oing request and my system answers with icmp reply) but the problem is, that
the src_adr of the esp_package is set to my local adr and not the adr of the
original esp-udp_packet sender ... so i try to use
sr.send
to send the message, but then i will have to create the whole header ... but
i dont't want to create it but copy it from the recived packet to the new
one ..
i hope you understand what i am trying to say ..

You just need the ipsec tools to generate the traffic i want to decapsulate.

Starting a GUI application out of an console application
Hello! I am currently working on an alternative for the gnome-volume-manager for multiseat systems based on HAL and DBus. Whenever the signal 'DeviceAdded' is received I would like to start a GUI-Interface where the user can choose from different options. But now I am wondering how I should start this interface since this GUI must be started by a console daemon. What is the most common way to do that? Usually, I start a PyQt application that way: app = QApplication(sys.argv) ui = Dialog() app.setMainWidget(ui) ui.show() app.exec_loop() If I start it that way, I am not quite sure whether this will work since I have got two main loops then (the one of console daemon [implemented by using gobject.MainLoop().run()] and the Qt one). Moreover, once the Qt application is started, it should run independently of the console daemon. Unfortunately, I can't think of any possibility to achieve this aim. Do you have any suggestions? -- http://mail.python.org/mailman/listinfo/python-list
Recursive function returning a list
Hello! I have got a Python "Device" Object which has got a attribute (list) called children which my contain several other "Device" objects. I implemented it this way in order to achieve a kind of parent/child relationship. Now I would like to get all children of a given "Device" object and thought that it would be the best way to use recursive function. This is what I got so far: def getAllChildren(self, children=[]): if self.children: children.extend(self.children) for child in self.children: child.getAllChildren(children) return children Unfortunately, it doesn't work like expected since the default parameter children=[] is evaluated only once. That's why the children list becomes larger and larger after calling the method several times but I can't think of another possibility.

Thanks! I found a different example too:
import ConfigParser
import string
config = ConfigParser.ConfigParser()
config.read("/home/fab/.abook/addressbook")
# print summary
print
for number in [2,200]:
print string.upper(config.get(str(number), "email"))
print string.upper(config.get(str(number), "name"))
print string.upper(config.get(str(number), "city"))
print string.upper(config.get(str(number), "address"))
but the problem seems to be that abook does not write every
field, so I get an exception when there is a field missing:
Traceback (most recent call last):

radio buttons in curses
Hi, I want to add some radio and check buttons to my curses script. As I understand it, there are no buttons in the 'basic' curses module. Now, I found the curses-extra module, but I not able to download and install it. Does anybody have an idea, where I can download the module or, even better, how I can create radio and check buttons with the 'ordinary' curses module? Would be nice... Greetings!

Flushing standard input
Recently I came across a problem which I still can't solve on my own.
Consider this small example:
import sys
import time
time.sleep(3)
print
sys.stdin.flush()
input = raw_input('Your input: ')
print 'Your input: ', input
While the script is sleeping I type in the word 'test1', so that it is
printed on the console. Having slept for three seconds the script
continues and wants me to type in another word 'test2' and I hit return.
The output looks like this:
[EMAIL PROTECTED] ~ [ 21:41:27 ] $ python test.py
test1
test2
Your input: test1test2
Is there any way to flush the stdin buffer so that 'test1' is _not_
regarded as input? How could one solve this issue?
Cheers,
Fabian

change keybindings for pygtk treeview
Hi, I am just testing pygtk/glade out and wonder, if I am able to change the keybindings. E.g. the treeview searches by default for the entries beginning with the typed keystroke; moving to the next row works as usual with the Down key. Now I would like to change the key bindings to e.g. 'j' to move to the next row (just like in vim) and to use a 'Ctrl' key combination to search for a certain word beginning with the typed key stroke. Is it anyhow possible with pygtk? Would be nice, if somebody can point my to a small example. Greetings! Fabian -- http://mail.python.org/mailman/listinfo/python-list

I just found out, that I am able to turn it of with
'treeview.set_enable_search(False)'. Works nice.
An option would be, to toggle the searching function with
some keystroke, e.g. 'Ctrl-s'. And set a key binding for the
movement to 'j' and 'k' when the search mode is disabled. I
think I could do it somehow with the 'accelgroup' function,
but did not find enough information to get a clue out of it.
Does anybody have an idea?
In a small curses based file manager (lfm) there is an
assignment of keybindings via a keytable
keytable = {
# movement
ord('p'): 'cursor_up',
ord('k'): 'cursor_up',
ord('K'): 'cursor_up2',
ord('P'): 'cursor_up',
curses.KEY_UP: 'cursor_up',
ord('n'): 'cursor_down',
ord('j'): 'cursor_down',
ord('J'): 'cursor_down2',
ord('N'): 'cursor_down',
...
Would that work in any way for a pygtk program too?
Greetings!

small python cgi webserver
Hi,
I am looking for a small python script, which starts a small
web server with python cgi support on a linux machine.
I tried:
#!/usr/bin/env python
import sys
from CGIHTTPServer import CGIHTTPRequestHandler
import BaseHTTPServer
class MyRequestHandler(CGIHTTPRequestHandler):
# In diesem Verzeichnis sollten die CGI-Programme stehen:
cgi_directories=["/home/fab/Desktop/cgi-bin"]
def run():
# 8000=Port-Nummer
# --> http://localhost:8000/
# Fuer http://localhost/
# Port-Nummer auf 80 setzen
httpd=BaseHTTPServer.HTTPServer(('', 8000), MyRequestHandler)
httpd.serve_forever()
if __name__=="__main__":
print "Starting Server"
run()
but when I want to test a small python cgi test file:
#!/usr/bin/python
# -*- coding: UTF-8 -*-
# Debugging fÃŒr CGI-Skripte 'einschalten'
import cgitb; cgitb.enable()
print "Content-Type: text/html;charset=utf-8\n"
print "Hello World!"
I just get the text and not the html output. The file's mode
is 755.
Is there anything wrong with the webserver script or do I do
something completely wrong? Maybe, you have a different
webserver script?
Greetings!

If you have a text like: Yes thats right, but that isn't my problem. The problem is in the "(?=(iface)|$)" part. I have i.e. the text: "auto lo eth0 iface lo inet loopback bla blub iface eth0 inet dhcp hostname debian" My regex should match the marked text. But it matchs the whole text starting from iface.

Splitting device addresses into parts
I often have to deal with strings like "PCI:2:3.0" or "PCI:3.4:0" and need the single numbers as tuple (2, 3, 0) or (3, 4, 0). Is there any simple way to achieve this?

Unfortunately, this doesn't work (even if I correct your typos) since
the delimeter isn't necessary a colon - that's exactly the difficulty I
am trying to solve.

python 2.5 install from source problem
Hi, I just tried to install python 2.5 from source on my ScienticLinux (Redhat Clone) machine. It seems to work without any problem, at least I am able to run some of my old scripts. I installed it with './configure --prefix=/opt/python make make altinstall', but now for a 'vtk' installation which needs the python libraries I am not able to find a file like 'libpython2.5.so.*', which I think should be produced (at least at my office's machine (redhat) it is there). I just can find a 'libpython2.5.a' file ... Do I do something wrong? Greetings! Fabian -- http://mail.python.org/mailman/listinfo/python-list

Hello! So far, I am using something like »if isinstance(var, int):« to determine, whether var's value is an integer.

Re: PyQt: QListView how to retrieve selected items?
Hi! Sorry for adopting your post for my own question, but since it is related to PyQT I think it's ok: Does anybody of you know where the openbook »GUI Programming with Python: QT Edition« has gone?

PyQt and Threading to update a dialog?
Hello! I have just written a MyDialog class which is derived from the orginial QDialog class. MyDialog only possesses a QLabel and a QPushButton. Now I would like to get the QLabel updated every second so that it displays the current time. I think I will have to work with Threads in order to achieve this aim, but so far I didn't succeed in doing it because I couldn't find any examples. Could anyone give me some hints or a piece of code? Cheers, Fabian Steiner -- http://mail.python.org/mailman/listinfo/python-list
PyQT: QDialog and QMainWindow interacting with each other
Hello!
I have got a QMainWindow with a QListView, in which the different
entries of a database are shown to the user. Moreover it has got a
QPushButton, so that another QDialog can be opened where the user is
able to add a new entry:
...
self.connect(self.btnNew, SIGNAL('clicked()'), self.openNewDialog)
...
def openNewDialog(self):
dialog = MyDialog(self)
dialog.show()
self.showListViewItems() # this line isn't recognized
MyDialog is closed by calling MyDialog.accept(). What can I do so that
self.showListViewItems() is called after MyDialog has been closed?
Thank you for any input!
Cheers,
Fabian Steiner

Printing a file
Hello! I am currently working on an application where the user is able to create new worksheets and to delete existing ones. All of these worksheets have the same structure (--> template?), only some values should be changed. A minimal example would be something like this: Name: ... Role: Address: The values are stored in a SQLite database. Now I would like to offer the possibility to print out a single record on a DinA4 paper. In order to do this, the dots (...) above of course have to be replaced by the current record's values and the different parts have to fit on one page. Unfortunately I don't know how to realize this, since also some images and different boxes should be printed out. As the whole application is based on QT, QPrinter might be used, but I couldn't find any examples how to use it. What do you suggest? Which format should the template have? (XML, etc.?) Any hints appreciated! Cheers, Fabian Steiner -- http://mail.python.org/mailman/listinfo/python-list

Thank you very much for this hint! Thanks to this example I was able to print out my first pages :) But some questions still remain. At the moment I am using QSimpleRichtext and a personal HTML-File. I had a look at the example.html of textedit.cpp (/usr/share/doc/qt-4.1.1/demos/textedit) and found out that it contains quite a lot of proprietary HTML elements, attributes and CSS style definitions. So far I didn't even know that QSimpleRichText even supports CSS since I couldn't find anything related to this point in the official docs (--> e.g. QStylesheet). Is there any tool out there with which I can write those special HTML files? I am quite familiar with HTML and CSS but I don't want to waste my time with that.

Thanks for your advice. This pointed me into the right direction.
For those who are interested the function passed to os.path.walk looks like
this:
def _chownRecursive(arg, dirname, fnames):
os.chown(dirname, arg[0], arg[1])
for file in fnames:
os.chown(os.path.join(dirname, file), arg[0], arg[1])

help with Python C-API, tuple object
Hi,
sorry for the rather basic question but I've searched everywhere and
don't find an answer.
I want to call PyObject_CallObject from the Python C-API and pass a
tuple I've created from a C-array
How can I pass the tuple as an object rather then having to declare
the python function with the number of arguments equal to the no of
elements in the tuple?
Example:
C-Code fragment:
PyObject *pArgs = PyTuple_New(3);
//module is imported and function object is build and checked
for (i=0; i<3; i++){
pInt = PyInt_FromLong(i);
error = PyTuple_SetItem(pArgs, i, pInt);
}
pValue=PyObject_CallObject(pFunc, pArgs);//returns NULL!!!
Python Script:
def length(a):
length = len(a)
return length

pattern search
Hi,
I wrote a small gtk file manager, which works pretty well. Until
now, I am able to select different file (treeview entries) just by
extension (done with 'endswith'). See the little part below:
self.pathlist1=[ ]
self.patternlist=[ ]
while iter:
#print iter
value = model.get_value(iter, 1)
#if value is what I'm looking for:
if value.endswith("."+ pattern):
selection.select_iter(iter)
selection.select_path(n)
self.pathlist1.append(n)
self.patternlist.append(value)
iter = model.iter_next(iter)
#print value
n=n+1
Now, I would like to improve it by searching for different 'real'
patterns just like using 'ls' in bash. E.g. the entry
'car*.pdf' should select all pdf files with a beginning 'car'.
Does anyone have an idea, how to do it?
Greetings!
Fabian

I have a already a list, but I 'glob' looked so easy ... maybe it is
faster to use fnmatch. When I have time I try it out...

open remote terminal
Hi, I would like to use python to start an terminal, e.g. xterm, and login on a remote machine using rsh or ssh. This could be done using 'xterm -e ssh machine', but after the login I would like to jump to a given directory. Does anyone have an idea how to do this with python? Regards! Fabian -- http://mail.python.org/mailman/listinfo/python-list
pyparsing batch file
Hi,
me again :-)
I would like to parse a small batch file:
file/read-case kepstop.cas
file/read-data keps1500.dat
solve/monitors/residual/plot no
solve/monitors/residual/print yes
/define/boundary-conditions in velocity-inlet 10 0.1 0.1 no 1
it 500
wd keps1500_500.dat
yes
exit
Right now, I use this little example:
from pyparsing import *
input =
open("/home/fab/HOME/Dissertation/CFD/Fluent/Batch/fluent_batch",
'r')
data = input.read()
#
# Define Grammars
#
integer = Word(nums)
hexnums = Word(alphanums)
end = Literal("\n").suppress()
all = SkipTo(end)
#threadname = dblQuotedString
threadname_read_case = Literal("file/read-case")
threadname_read_data= Literal("file/read-data")
threadname_it = Literal("it")
write_data=Literal("wd")
cas_datei= Word(alphanums)
iteration= Word(nums)
write= Word(alphanums)
file_read_data= "file/read-data " + hexnums.setResultsName("rd")
logEntry = threadname_read_case.setResultsName("threadname")
+ cas_datei.setResultsName("cas_datei")+file_read_data
logEntry = file_read_data
logEntryNew = threadname_it.setResultsName("threadname") +
iteration.setResultsName("iteration")
logEntryWD = write_data.setResultsName("threadname") +
write.setResultsName("write")
#
for tokens in logEntryNew.searchString(data):
print
print "Iteration Command=\t "+ tokens.threadname
print "Number of Iterations=\t "+ tokens.iteration
for x in tokens.condition:
print x
print 50*"-"
for tokens in logEntryWD.searchString(data):
print
print "Write Data Command=\t "+ tokens.threadname
print "Data File Name=\t "+ tokens.write
for x in tokens.condition:
print x
print 50*"-"
for tokens in logEntry.searchString(data):
print
print "no idea=\t "+ tokens.threadname
print "Data File=\t "+ tokens.rd
print
for x in tokens.condition:
print x
print 50*"-"
Unfortunately, it does not parse the whole file names with
the underscore and I do not know yet, how I can access the
line with 'define/boundary-conditions'. Every 'argument' of
that command should become a separate python variable!?
Does anyone have an idea, how I can achieve this!?
Regards!

Unfortunately nothing happens expect the start of xterm!? Does anyone have

ignoring chinese characters parsing xml file
Hi, I am parsing an XML file that includes chineses characters, like ^ �u�u啖啖才是�w.���扉L锍才是�� or ヘアアイロン... The problem is that I get an error like: UnicodeEncodeerror:'charmap' codec can't encode characters in position The thing is that I would like to ignore it and parse all the characters less these ones. So, could anyone help me? I suppose that I can catch an exception that ignores it or maybe use any function that detects this chinese characters and after that ignore them. Thanks!!

Re: ignoring chinese characters parsing xml file
Thanks Mark, the code is like this. The attrib name is the problem:
from lxml import etree
context = etree.iterparse("file.xml")
for action, elem in context:
if elem.tag == "weblog":
print action, elem.tag , elem.attrib["name"],elem.attrib["url"],
elem.attrib["rssUrl"]
And the xml file like:

Re: ignoring chinese characters parsing xml file
Thanks, I have tried all you told me. It was an error on print statement. So
I decided to catch the exception if I had an UnicodeEncodeError, that is, if
I had chinese/japanese characters because they don't interest to me and it
worked.
The strip_asian function of Ryan didn't work well here, but it's a good idea
for next goals.
Thanks a lot!

How to test whether a host is reachable?
Hello!
As the subject says I need to test whether a host computer in our
network is reachable or not. At the moment I simply attempt to connect
to a given port that is open when the machine is online:
[...]
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try:
sock.connect(('192.168.0.100', 80))
except socket.error:
print >>sys.stderr "Server offline"
sock.close()
[...]
Now I am wondering if there isn't any better method which would be more
general. In fact, I think of something like a python version of ping
which only tries to send ICMP packets. However, I don't know what the
code has to look like then. Any ideas or suggestions?
Thanks,
Fabian

crawler in python and mysql
Hi, I would like to write a code that needs to crawl an url and take all the HTML code. I have noticed that there are different opensource webcrawlers, but they are very extensive for what I need.

Efficient: put Content of HTML file into mysql database
Hi colegues, do you know the most efficient way to put the content of an html file into a mySQL database?Could it be this one?: 1.- I have the html document in my hard disk. 2.- Then I Open the file (maybe with fopen??) 3.- Read the content (fread or similar) 4.- Write all the content it in a SQL sentence. What happens if the html file is very big? Thanks! FAbian -- http://mail.python.org/mailman/listinfo/python-list
Re: Efficient: put Content of HTML file into mysql database
Thanks Jesse, we have a webserver with different domains and I need to crawl different urls so I decided first to download the file using : f = urllib.urlretrieve(url,'doc.html') And after that, I will read the content with all the HTML tags and save it on our database in order to work with this text. Is it enough? it is such an easy web crawler. Maybe I can save it without downloading the file, can I?

the word "README_x.org", where x is any number.
E.g. the structure would look like this:
[[file:~/pfm_v99/README_1.org]]
I tried to use these kind of matchings:
#org_files='.*README\_1.org]]'
org_files='.*README\_*.org]]'
if re.match(org_files,line):
Unfortunately, it matches all entries with "README.org", but
not the wanted number!?
After some splitting and replacing I am able to check, if
the above file exists. If it does not, I start to search for
it using the 'walk' procedure:
for root, dirs, files in
os.walk("/home/fab/org"):
for name in dirs:
dirs=os.path.join(root, name) + '/'
for name in files:
files=os.path.join(root, name)
if fnmatch.fnmatch(str(files), "README*"):
print "File Found"
print str(files)
break
As soon as it finds the file, it should stop the searching
process; but there is the same matching problem like above.
Does anyone have any suggestions about the regex problem?
Greetings!
Fabian

Thanks a lot, works really nice!

lotus nsf to mbox
Hi, I am wondering, if anyone tried to convert lotus nsf mails to a mbox format using python!? It would be nice, if anyone has an idea, how to do it on a linux machine. Regards! Fabian -- http://mail.python.org/mailman/listinfo/python-list

problem with array and for loop
Hi, I have a 'simple' problem with a multidimension array in a for loop. It looks like this: wert= zeros([127,2]) wert1= zeros(127) m=1 l=1 for pos in [pos1,pos2,pos3]: for i in range(1,125): wert[l,m]= probe1.GetOutput().GetPointData().GetScalars().GetTuple1(i); #wert1[i]= probe1.GetOutput().GetPointData().GetScalars().GetTuple1(i); m=m+1; l=l+1; It works for the 1D 'wert1'. Does anyone have an idea? Greetings! Fabian -- http://mail.python.org/mailman/listinfo/python-list

However, wert only has two columns. Thanks!

Selecting multiple directories (TKinter)
Hi, I'm currently using tkFileDialog.askdirectory() to select a single directory. I would like to be able to select multiple directories. tkFileDialog.askopenfilenames() seems to do this for files. What can I do in my situation? Are there alternative classes that provide file dialogs better suited for my purpose? Thanks! Fabian -- http://mail.python.org/mailman/listinfo/python-list
Measuring time of a telnet connect
Hi! I want to realize the following: I want to measure the time it takes to build up a telnet connection to a known host (ip/port). I tried to use subprocess.Popen to build the telnet connection and then to catch the "Trying to connect..." and "Connection established" output. But this didn't work - both had always the same timestamp (time.time()) - i think that's due to some buffers. Has anyone an idea how to solve this? Tanks in advance.. -- http://mail.python.org/mailman/listinfo/python-list

C-API: A beginner's problem
I recently started learning C since I want to be able to write Python
extension modules. In fact, there is no need for it, but I simply want
to try something new ...
I tried to implement the bubblesort algorithm in C and to use it in
python; bubblesort.c compiles fine, but whenever I want to import the
modul and call the function I get a segmentation fault. This is what the
code looks like:
static PyObject *py_bubblesort(PyObject *self, PyObject *args) {
PyObject *seq = NULL, *item, *newseq = NULL;
int seqlen, i;
if(!PyArg_ParseTuple(args, "O", &seq)) {
return NULL;
}
seq = PySequence_Fast(seq, "argument must be iterable");
if(!seq) {
return NULL;
}
seqlen = PySequence_Fast_GET_SIZE(seq);
int list[seqlen];
for (i = 0; i <= seqlen; i++) {
item = PySequence_Fast_GET_ITEM(seq, i);
list[i] = item;
}
bubblesort(list, seqlen);
newseq = PyList_New(seqlen);
if(!newseq) {
return NULL;
}
for(i = 0; i < seqlen; i++) {
PyList_SetItem(newseq, i, list[i]);
}
return newseq;
bubblesort(int list[], int seqlen) is doing the actual job and it is
working.
What did I do wrong? As I am quite new to C, I probably made many
mistakes, so please feel free to correct me.
Cheers,
Fabian
