I've been working on this problem for hours now and I can't get this to work. I've tried doing this algorithm on paper and it works just fine.. Could you give me hints what's wrong ?
Is there a way to test the html from the response of:
response = self.client.get('/user/login/')
I want a detailed check like input ids, and other attributes. Also, how about sessions that has been set? is it possible to check their values in the test?
I am programming in Visual Studio 2010, using TortiseSVN and VisualSVN as my client to connect to SVN repositories.
I am having a bit of a frequent problem though with the whole SVN thing in general. One thing that keeps cropping up is that if I make changes to files - namely filenames, or move them to new folders, etc, I end up getting all kinds of conflicts with the repository and it just causes all sorts of strange errors.
I understand the importance of version control and check-in/check-out access like this, but what do most of you do to deal with this kind of thing? I mean, I've tried doing the whole 'Remove from Subversion', change my file, then 'Add to Subversion' thing, and it just doesn't seem to do the job very well. This is especially frustrating when working on web projects where filenames can change very frequently as a project evolves and becomes multifaceted.
Are there any standard ways to deal with this kind of thing, or is it just one of the flaws of SVN in general?
MYMESSAGE = "<div>Hello</div><p></p>Hello"
send_mail("testing",MYMESSAGE,"[email protected]",['[email protected]'],fail_silently=False)
However, this message doesn't get the HTML mime type when it is sent. In my outlook, I see the code...
I know this title look familiar to some old questions, but i've looked at every single one of them, none of them solves.
And here is my codes:
class Island (object):E,W,R,P
def __init__(self, x, y):
self.init_animals(y)
def init_animals(y):
pass
isle = Island(x,y)
However, i got the following error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 3, in __init__
TypeError: init_animals() takes 1 positional arguments but 2 were given
Please tell me if i got any mistakes, im so confused by this.
Best regards
This is a module named XYZ.
def func(x)
.....
.....
if __name__=="__main__":
print func(sys.argv[1])
Now I have imported this module in another code and want to use the func. How can i use it?
import XYZ
After this, where to give the argument, and syntax on how to call it, please?
I am trying some simple c API, where I am using PyCapsule_New to encapsulate a pointer. I am running into segment violation, can some body help me.

Write an iterative program that finds the largest number of McNuggets that cannot be bought in exact quantity. Your program should print the answer in the following format (where the correct number is provided in place of n):
"Largest number of McNuggets that cannot be bought in exact quantity: n"
I am working on large numpy arrays, and some native numpy operations are too slow for my needs (for example simple operations such as "bitwise" A&B).
I started looking into writing C extensions to try and improve performance. As a test case, I tried the example given here, implementing a simple trace calculation. I was able to get it to work, but was surprised by the performance: for a (1000,1000) numpy array, numpy.trace() was about 1000 times faster than the C extension!
This happens whether I run it once or many times. Is this expected? Is the C extension overhead that bad? Any ideas how to speed things up?
I am the create_user() function that Django provides to create my users. Also I want to store additional information about the users. So I tried following the instructions given at
http://docs.djangoproject.com/en/dev/topics/auth/#storing-additional-information-about-users
but I cannot get it to work for me. Is there a step-by-step guide that I can follow to get this to work for me?
Also, once I have added these custom fields, I would obviously need to add / edit / delete data from them. I cannot seem to find any instructions on how to do this.
The title says it all. The objective is to have two simple ways to source some code, say func.R, containing a function. Calling R CMD BATCH func.R initializes the function and evaluates is. Within a session, issuing source("func.R") simply initializes the function.
Any idea?
I have written the following script. It opens a file, reads each line from it splitting by new line character and deleting first character in line. If line exists it's being added to array. Next each element of array is splitted by whitespace, sorted alphabetically and joined again. Every line is printed because script is fired from console and writes everything to file using standard output. I'd like to optimize this code to be more pythonic. Any ideas ?
import sys
def main():
filename = sys.argv[1]
file = open(filename)
arr = []
for line in file:
line = line[1:].replace("\n", "")
if line:
arr.append(line)
for line in arr:
lines = line.split(" ")
lines.sort(key=str.lower)
line = ''.join(lines)
print line
if __name__ == '__main__':
main()

On example, i have 2 apps: alpha and beta
in alpha/models.py import of model from beta.models
and in beta/models.py import of model from alpha.models
manage.py validate says that ImportError: cannot import name ModelName
how to solve this problem?
A minimal example:
class MainWindow(QtGui.QMainWindow):
def __init__(self, parent = None):
QtGui.QMainWindow.__init__(self, parent)
winWidth = 683
winHeight = 784
screen = QtGui.QDesktopWidget().availableGeometry()
screenCenterX = (screen.width() - winWidth) / 2
screenCenterY = (screen.height() - winHeight) / 2
self.setGeometry(screenCenterX, screenCenterY, winWidth, winHeight)
layout = QtGui.QVBoxLayout()
layout.addWidget(FormA())
mainWidget = QtGui.QWidget()
mainWidget.setLayout(layout)
self.setCentralWidget(mainWidget)
FormA is a QFrame with a VBoxLayout that can expand to an arbitrary number of entries.
In the code posted above, if the entries in the forms can't fit in the window then the window itself grows. I'd prefer for the window to become scrollable. I've also tried the following...
replacing
mainWidget = QtGui.QWidget()
mainWidget.setLayout(layout)
self.setCentralWidget(mainWidget)
with
mainWidget = QtGui.QScrollArea()
mainWidget.setLayout(layout)
self.setCentralWidget(mainWidget)
results in the forms and entries shrinking if they can't fit in the window.
Replacing it with
mainWidget = QtGui.QWidget()
mainWidget.setLayout(layout)
scrollWidget = QtGui.QScrollArea()
scrollWidget.setWidget(mainWidget)
self.setCentralWidget(scrollWidget)
results in the mainwidget (composed of the forms) being scrunched in the top left corner of the window, leaving large blank areas on the right and bottom of it, and still isn't scrollable.
I can't set a limit on the size of the window because I wish for it to be resizable.
How can I make this window scrollable?

Hey,
I'm running a function which evaluates commands passed in using stdin and another function which runs a bunch of jobs. I need to make the latter function sleep at regular intervals but that seems to be blocking the stdin. Any advice on how to resolve this would be appreciated.
The source code for the functions is
def runJobs(comps, jobQueue, numRunning, limit, lock):
while len(jobQueue) >= 0:
print(len(jobQueue));
if len(jobQueue) > 0:
comp, tasks = find_computer(comps, 0);
#do something
time.sleep(5);
def manageStdin():
print "Global Stdin Begins Now"
for line in fileinput.input():
try:
print(eval(line));
except Exception, e:
print e;
--Thanks
Over the years, I've built up a number of macros that I like to have available in visual studio.
It's always a pain to reload them and rebind them to the keyboard when I go to a different machine/rebuild/use a VM/etc.
Someone mentioned to me once that there is a way that you can write a macro that will recreate your macros and bind them to keys automatically. Anyone know how to do that? Is there another way to easily export/import macros (nonsensically, VS has an "export macro" function, but no import).
I've a model called broadcastinfo, It has fields viz.. info,userid...userid is excluded. when i add an new info, my broadcastinfo table should get the records of all userid from user table and the given message. Im trying this via signal.Any idea is highly appreciated.
Thanks
Hello, I am trying to use RE to match a changing ID and extract it. I am having some bother getting it working. The String is:
m = 'Some Text That exists version 1.0.41.476 Fri Jun 4 16:50:56 EDT 2010'
The code I have tried so far is:
r = re.compile(r'(s*\s*)(\S+)')
m = m.match(r)
Can anyone help extract this string.
Thanks
I happened to find myself having a basic filtering need: I have a list and I have to filter it by an attribute of the items.
My code looked like this:
list = [i for i in list if i.attribute == value]
But then i thought, wouldn't it be better to write it like this?
filter(lambda x: x.attribute == value, list)
It's more readable, and if needed for performance the lambda could be taken out to gain something.
Question is: are there any caveats in using the second way? Any performance difference? Am I missing the Pythonic Way™ entirely and should do it in yet another way (such as using itemgetter instead of the lambda)?
Thanks in advance
I have a table with an 'expires' datetime column. I want to find all the items that have an 'expires' date earlier than now.
I've tried
session.query(Item).filter(Item.expires < now())
but it doesn't return anything regardless of the dates in the table.
I'm using PostgreSQL 8.4.
How do I do this comparison?
