class Test:
def test(self, p, d={}):
d.update(p)

print inspect.getargspec(getattr(Test, 'test'))[3]
print Test().test({'1':True})
print inspect.getargspec(getattr(Test, 'test'))[3]
I would expect the argspec for Test.test not to change but because of dict.update it does. Why?
I have a table, Foo. I run a query on Foo to get the ids from a subset of Foo. I then want to run a more complicated set of queries, but only on those IDs. Is there an efficient way to do this? The best I can think of is creating a query such as:
SELECT ... --complicated stuff
WHERE ... --more stuff
AND id IN (1, 2, 3, 9, 413, 4324, ..., 939393)
That is, I construct a huge "IN" clause. Is this efficient? Is there a more efficient way of doing this, or is the only way to JOIN with the inital query that gets the IDs? If it helps, I'm using SQLObject to connect to a PostgreSQL database, and I have access to the cursor that executed the query to get all the IDs.
Does anyone know Twitter's rate limit on posting? Looking at their web page they claimed to not have one but I get an exception thrown if my program posts too fast... Any help is appreciated.
Is it possible to get the name of a node using minidom?
for example i have a node:
<heading><![CDATA[5 year]]></heading>
what i'm trying to do is store the value heading so that i can use it as a key in a dictionary,
the closest i can get is something like
[<DOM Element: heading at 0x11e6d28>]
i'm sure i'm overlooking something very simple here, thanks!
When declaring a class that inherits from a specific class:
class C(dict):
added_attribute = 0
the documentation for class C lists all the methods of dict (either through help(C) or pydoc).
Is there a way to hide the inherited methods from the automatically generated documentation (the documentation string can refer to the base class, for non-overwritten methods)? or is it impossible?
This would be useful: pydoc lists the functions defined in a module after its classes. Thus, when the classes have a very long documentation, a lot of less than useful information is printed before the new functions provided by the module are presented, which makes the documentation harder to exploit (you have to skip all the documentation for the inherited methods until you reach something specific to the module being documented).
i have a directory with around 1000 files....i want to run a same code for each of these file...
my code requires the file name to be inputted.
i have written code to copy the information of one into other in other format...
please suggest a method to copy all 1000 files one by one without need to change the file name every time
and i have a field serial_num which need to be continous i.e if 1st file has upto 30 then while coping other file it should continue from 30not from 0 again
require suggestion please
thanks..
Hello to all!
I am writing a small Django application and I should be able to create
for each model object its periodical task which will be executed with
a certain interval. I'm use for this a Celery application, but i can't understand one thing:
class ProcessQueryTask(PeriodicTask):
run_every = timedelta(minutes=1)
def run(self, query_task_pk, **kwargs):
logging.info('Process celery task for QueryTask %d' %
query_task_pk)
task = QueryTask.objects.get(pk=query_task_pk)
task.exec_task()
return True
Then i'm do following:
>>> from tasks.tasks import ProcessQueryTask
>>> result1 = ProcessQueryTask.delay(query_task_pk=1)
>>> result2 = ProcessQueryTask.delay(query_task_pk=2)
First call is success, but other periodical calls returning the error
- TypeError: run() takes exactly 2 non-keyword arguments (1 given) in
celeryd server.
So, can i pass own params to PeriodicTask run() ?
Thanks!
Is there any library that achieves the following:
Convert
Microsoft Windows 98
Microsoft Windows XP
Windows 7
Windows Ultimate
Desktop Windows
to
Windows 4
The complicated part here is to recognize that "Desktop Windows" is an anomaly here and not count it. If nothing is added before the word "Windows", perhaps it can be counted but if there is something else and the suffix does not match any popular suffix, it can still be counted.
Maybe I am a little vague here but perhaps someone could have an idea about what I am talking about here. Any suggestions?
Hello,
I have 3 panels and I want to make drags on them.
The problem is that when I do a drag on one this happens:
How can I refresh the frame to happear its color when the panel is no longer there?
We've had some good experiences building an app on Google App Engine, this first app's target audience are Google Apps users, so no issues there in terms of it being hosted on Google infrastructure.
We like it so much that we would like to investigate using it for a another app, however this next project is for a client who is not really that interested in what technology it sits on, they just want it to work, and work all of the time.
In this scenario, given that we have the technology applicability and capability side covered, are there any concerns that this stuff is still relatively new and that we may not be as much "in control" as if we had it done with traditional hosting?
More specifically I'm looking for something, perhaps an add-on for firefox, once enabled it logs all of this information as it's passed to and from the server. I'm doing some web scripting and this would be really handy.
If anyone is wondering specifically what I'm doing currently I'm trying to make a script to repost my craigslist ad every 2 days since I handle a few things on there. Might even go so far as to make a simple gui to manage the submissions.
I do suspect this goes against the ToS, for that reason I don't plan to release the code. Besides cl is already bad enough with spam, I'm not trying to contribute further to it, figured I'd say what I'm doing for the sake of being honest though. I don't have any bad intentions with this, just some things I've been trying to sell an ad for my pc repair business. I've been reposting some things for months now and so often I just forget to do it.
Ok, so I've written some code that, for all intents and purposes, should work:
def checkComments(comments):
for comment in comments:
print comment.body
checkComments(comment.replies)
def processSub(sub):
sub.replace_more_comments(limit=None, threshold=0)
checkComments(sub.comments)
#login and subreddit init stuff here
subs = mysubreddit.get_hot(limit=50)
for sub in subs:
processSub(sub)
However, given a submission that has 50 nested replies like so:
root comment
-> 1st reply
-> 2nd reply
-> 3rd reply
...
-> 50th reply
The above code only prints:
root comment
1st reply
2nd reply
3rd reply
4th reply
5th reply
6th reply
7th reply
8th reply
9th reply
Any idea how I can get the remaining 41 levels of replies? Or is this a praw limitation?

For formatting a date using date filter you must use the following format :
{{ my_date|date:"Y-m-d" }}
If you use strftime from the standard datetime, you have to use the following :
my_date.strftime("%Y-%m-%d")
So my question is ... isn't it ugly (I guess it is because of the % that is used also for tags, and therefore is escaped or something) ?
But that's not the main question ... I would like to use the same DATE_FORMAT parametrized in settings.py all over the project, but it therefore seems that I cannot ! Is there a work around (for example a filter that removes the % after the date has been formatted like {{ my_date|date|dream_filter }}, because if I just use DATE_FORMAT = "%Y-%m-%d" I got something like %2001-%6-%12)?
I have around 20 functions (is_func1, is_fucn2, is_func3...) returning boolean
I assume there is only one function which returns true and I want that!
I am doing:
if is_func1(param1, param2):
# I pass 1 to following
abc(1) # I pass 1
some_list.append(1)
elif is_func2(param1, param2):
# I pass 2 to following
abc(2) # I pass 1
some_list.append(2)
...
.
.
elif is_func20(param1, param2):
...
Please note: param1 and param2 are different for each, abc and some_list take parameters depending on the function.
The code looks big and there is repetition in calling abc and some_list, I can pull this login in a function! but is there any other cleaner solution?
I can think of putting functions in a data structure and loop to call them.
My test code is as follows, using threading, count is not 5,000,000 , so there has been data race, but using gevent, count is 5,000,000, there was no data race .
Is not gevent coroutine execution will atom "count + = 1", rather than split into a one CPU instruction to execute?
# -*- coding: utf-8 -*-
import threading
use_gevent = True
use_debug = False
cycles_count = 100*10000
if use_gevent:
from gevent import monkey
monkey.patch_thread()
count = 0
class Counter(threading.Thread):
def __init__(self, name):
self.thread_name = name
super(Counter, self).__init__(name=name)
def run(self):
global count
for i in xrange(cycles_count):
if use_debug:
print '%s:%s' % (self.thread_name, count)
count = count + 1
counters = [Counter('thread:%s' % i) for i in range(5)]
for counter in counters:
counter.start()
for counter in counters:
counter.join()
print 'count=%s' % count
I want get the details of the wave such as its frames into a array of integers.
Using fname.getframes we can ge the properties of the frame and save in list or anything for writing into another wav or anything,but fname.getframes gives information not in integers some thing like a "/xt/x4/0w' etc..
But i want them in integer so that would be helpful for manupation and smoothening join of 2 wav files
I have a folder full of files and i want to search some string inside them. The issue is that some files may be zip,exe,ogg,etc.
Can i check somehow what kind of file is it so i only open and search through txt, php, etc files.
I can't rely on the file extension.
Hi everyone.
This question is in continuation to my previous question, in which I asked about passing around an ElementTree.
I need to read the XML files only and to solve this, I decided to create a global ElementTree and then parse it wherever required.
My question is:
Is this an acceptable practice? I heard global variables are bad. If I don't make it global, I was suggested to make a class. But do I really need to create a class? What benefits would I have from that approach. Note that I would be handling only one ElementTree instance per run, the operations are read-only. If I don't use a class, how and where do I declare that ElementTree so that it available globally? (Note that I would be importing this module)
Please answer this question in the respect that I am a beginner to development, and at this stage I can't figure out whether to use a class or just go with the functional style programming approach.
Currently I have a website on the Google App Engine written in Google's webapp framework. What I want to know is what are the benefits of converting my app to run with django? And what are the downsides? Also how did you guys code your GAE apps? Did you use webapp or django? Or did you go an entirely different route and use the Java api?
Thanks
