I have created an XML file using python. But the XML declaration has only version info. How can I include encoding with XML declaration like:
<?xml version="1.0" encoding="UTF-8"?>
There are times that I automagically create small shell scripts from Python, and I want to make sure that the filename arguments do not contain non-escaped special characters. I've rolled my own solution, that I will provide as an answer, but I am almost certain I've seen such a function lost somewhere in the standard library. By “lost” I mean I didn't find it in an obvious module like shlex, cmd or subprocess.
Do you know of such a function in the stdlib?
Hi,
I'd like to write some Python unit tests for my Google App Engine. How can I set that up? Does someone happen to have some sample code which shows how to write a simple test?
Hi,
My requirement is to search for jpeg images files in a directory using python script and list the file names. Can anyone help me on how to identify jpeg images files.
Thanks in advance...
Hello.
I'm having a problem with the module subprocess.
I'm running a script from python through:
subprocess.Popen('./run_pythia.sh',shell=True).communicate()
and sometimes it just blocks and it doesn't finish to execute the script. Before I was using .wait() instead of .communicate() but then because of this:
http://dcreager.net/2009/08/06/subprocess-communicate-drawbacks/
I changed to .communicate(). Nevertheless the problem continues.
Can anyone help me?
I have an RRD database, and I want to parse some of the data in it. I found this:
http://pypi.python.org/pypi/PyRRD/0.0.7
but it basically just calls the command line tools (no parsing).
Does anyone know of a library that will actually parse the output of rrdtool dump?
Thanks!
Consider this Python code for printing a list of comma separated values
for element in list:
print element + ",",
What is the preferred method for printing such that a comma does not appear if element is the final element in the list.
ex
a = [1, 2, 3]
for element in a
print str(element) +",",
output
1,2,3,
desired
1,2,3
I'd like to iterate over a list in Python several (say, 10) elements at a time, processing each slice one by one. I can think of a few ways to do this, but none seems obvious and clean. What is the most Pythonic way to do this?
Hi.
Is there any way to control links browser from python?
I need to make some bot, twill don't work on my page, Selenium need's X server.
Maybe other way to do it?
Total Python newb here. I have a images directory and I need to return the names and urls of those files to a django template that I can loop through for links. I know it will be the server path, but I can modify it via JS. I've tried os.walk, but I keep getting empty results.
Hi all,
Is there a cross-platform way of getting the path to the temp directory in Python 2.6?
For example, under Linux that would be /tmp, while under XP C:\Documents and settings\\[user]\Application settings\Temp.
Thanks!
Looking to put together a 3D side-scrolling action platformer. Since this is my first time trying to put together a non-simple adventure game, I'm at a loss for which engine to consider.
I would prefer one that supports scripting in python, since that's my primary language. Without tight controls, the game will suck... so speed is a priority. Cross-platform is also important to me.
Any suggestions?
I am writing a forum in Python. I want to strip input containing the right-to-left mark and things like that. Suggestions? Possibly a regular expression?
Does Python have a pool of all strings and are they (strings) singletons there?
More precise, in the following code one or two strings were created in memory:
a = str(num)
b = str(num)
?
I need to send a SOAP message (with Python SUDS) with strings encoded in 'iso-8859-2'.
Does anybody know how to do it?
SUDS raises the following exception when I invoke a method on a client with parameters encoded in 'iso-8859-2':
File "/home/bartek/myenv/lib/python2.5/site-packages/suds/sax/text.py", line 43, in __new__
result = super(Text, cls).__new__(cls, *args, **kwargs)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc5 in position 10: ordinal not in range(128)
My emacs hangs (Ubuntu 9 + emacs 23 + pyflakes) when I type """ quotes for string blocks.
anybody experience the same problem? I think, it may not be the emacs problem but some python mode or pyflakes which I use it for error checking.
Anybody hot around the issue? It really frustrating experience.
This might be a really dumb question, however i've looked around online, etc. And have not seen a solid answer.
What i was wondering, is there a simple way to do something like this?
lines = open('something.txt', 'r').readlines()
for line in lines:
if line == '!':
# force iteration forward twice
line.next().next()
<etc>
Is there an easy way to do that in python?
I am running ipython from sage and also am using some packages that aren't in sage (lxml, argparse) which are installed in my home directory. I have therefore ended up with a $PYTHONPATH of
$HOME/sage/local/lib/python:$HOME/lib/python
Python is reading and processing the first easy-install.pth it finds ($HOME/sage/local/lib/python/site-packages/easy-install.pth) but not the second, so eggs installed in $HOME/lib/python aren't added to the path. On reading the off-the-shelf site.py, I cannot for the life of me see why it's doing this.
Can someone enlighten me? Or advise how to nudge Python into reading both easy-install.pth files?
Consolidating both into one .pth file is a viable workaround for now, so this question is mostly for curiosity value.
I'm looking for a way to prevent multiple hosts from issuing simultaneous commands to a Python XMLRPC listener. The listener is responsible for running scripts to perform tasks on that system that would fail if multiple users tried to issue these commands at the same time. Is there a way I can block all incoming requests until the single instance has completed?
Can python retrieve the name of the user that owns a windows service?
I've had a fiddle with win32serviceutil but to no avail, nor can I find much documentation on it beyond starting and stopping services.
Thanks!
Is there a way to get the ceil of a high precision Decimal in python?
>>> import decimal;
>>> decimal.Decimal(800000000000000000001)/100000000000000000000
Decimal('8.00000000000000000001')
>>> math.ceil(decimal.Decimal(800000000000000000001)/100000000000000000000)
8.0
math rounds the value and returns non precise value
