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"?>
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!
I want to configure my Python logger in such a way so that each instance of logger should log in a file having the same name as the name of the logger itself.
e.g.:
log_hm = logging.getLogger('healthmonitor')
log_hm.info("Testing Log") # Should log to /some/path/healthmonitor.log
log_sc = logging.getLogger('scripts')
log_sc.debug("Testing Scripts") # Should log to /some/path/scripts.log
log_cr = logging.getLogger('cron')
log_cr.info("Testing cron") # Should log to /some/path/cron.log
I want to keep it generic and dont want to hardcode all kind of logger names I can have. Is that possible?
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 retrieved the data encoded in big5 from database,and I want to send the data as email of html content, the code is like this:
html += """<tr><td>"""
html += """unicode(rs[0], 'big5')""" # rs[0] is data encoded in big5
I run the script, but the error raised: UnicodeDecodeError: 'ascii' codec can't decode byte......
However, I tried the code in interactive python command line, there are no errors raised, could you give me the clue?

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
Is anyone having experience working with pycassa I have a doubt with it. How do I get all the keys that are stored in the database?
well in this small snippet we need to give the keys in order to get the associated columns (here the keys are 'foo' and 'bar'),that is fine but my requirement is to get all the keys (only keys) at once as Python list or similar data structure.
cf.multiget(['foo', 'bar'])
{'foo': {'column1': 'val2'}, 'bar': {'column1': 'val3', 'column2': 'val4'}}
Thanks.
Is there a way in python to turn a try/except into a single line?
something like...
b = 'some variable'
a = c | b #try statement goes here
Where b is a declared variable and c is not... so c would throw an error and a would become b...
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)
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 have a list in python ('A','B','C','D','E'), how do I get which item is under a particular index number?

Given 2, it would return C.
Given 4, it would return E.

How would I convert test cases made by Selenium IDE to Python without exporting every test case by hand? Is there any command line converter for that job?
In the end I want to use Selenium RC and Pythons build in unittest to test my websites.
Thanks a lot.
I'd like to have a Python program start listening on port 80, but after that execute without root permissions. Is there a way to drop root or to get port 80 without it?
In Python I have a list of n lists, each with a variable number of elements. How can I create a single list containing all the possible permutations:
For example
[ [ a, b, c], [d], [e, f] ]
I want
[ [a, d, e] , [a, d, f], [b, d, e], [b, d, f], [c, d, e], [c, d, f] ]
Note I don't know n in advance. I thought itertools.product would be the right approach but it requires me to know the number of arguments in advance
All the examples I've seen of sock.listen(5) in the python documentation suggest I should set the max backlog number to be 5. This is causing a problem for my app since I'm expecting some very high volume (many concurrent connections). I set it to 200 and haven't seen any problems on my system, but was wondering how high I can set it before it causes problems..
Anyone know?
I am just getting into Python development and would like to know which single IDE or editor is the best.
I mainly use Linux, but don't let that stop you if you think the best one is Win/Mac only.
I've a python script that gives me 2 lists and another who is the reference(the time).
How can I create a graphic with the representation of my first list by the time. And same question for the second list. I need them on the same graphic.
list1 [12, 15, 17, 19]
list2 [34, 78, 54, 67]
list3 [10, 20, 30, 40] (time in minutes)
How can I create a graphic in png format with these lists?
Thanks
Hi.
I'm implementing a RESTful web service in python and would like to add some QOS logging functionality by intercepting function calls and logging their execution time and so on.
Basically i thought of a class from which all other services can inherit, that automatically overrides the default method implementations and wraps them in a logger function. What's the best way to achieve this?
I want to produce a JSON file, containing some initial parameters and then records of data like this:
{
"measurement" : 15000,
"imi" : 0.5,
"times" : 30,
"recalibrate" : false,
{
"colorlist" : [234, 431, 134]
"speclist" : [0.34, 0.42, 0.45, 0.34, 0.78]
}
{
"colorlist" : [214, 451, 114]
"speclist" : [0.44, 0.32, 0.45, 0.37, 0.53]
}
...
}
How can this be achieved using the Python json module? The data records cannot be added by hand as there are very many.
Is it possible to perform multi-linear regression in Python using NumPy?
The documentation here suggests that it is, but I cannot find any more details on the topic.
Hi folks,
I'm using the timeout parameter within the urllib2's urlopen.
urllib2.urlopen('http://www.example.org', timeout=1)
How do I tell Python that if the timeout expires a custom error should be raised?
Any ideas?
