Hello,
I'm making a toolbar using wxpython and I want to put the Quit button on the right side of it, I don't want to put them sequencially.
Is it possible to define this position?
Thanks in advance!
If I want to split a list of words separated by a delimiter character, I can use
>>> 'abc,foo,bar'.split(',')
['abc', 'foo', 'bar']
But how to easily and quickly do the same thing if I also want to handle quoted-strings which can contain the delimiter character ?
In: 'abc,"a string, with a comma","another, one"'
Out: ['abc', 'a string, with a comma', 'another, one']
Related question: How can i parse a comma delimited string into a list (caveat)?
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.
Currently, i am querying with this code: meta.Session.query(Label).order_by(Label.name).all()
and it returns me objects sorted by Label.name in this manner ['1','7','1a','5c']. Is there a way i can have the objects returned in the order with their Label.name sorted like this ['1','1a','5c','7']
Thanks!
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.
I have a form in which I can input text through text boxes.
How do I make these data go into the db on clicking submit.
this is the code of the form in the template.
<form method="post" action="app/save_page">
<p>
Title:<input type="text" name="title"/>
</p>
<p>
Name:<input type="text" name="name"/>
</p>
<p>
Phone:<input type="text" name="phone"/>
</p>
<p>
Email:<input type="text" name="email"/>
</p>
<p>
<textarea name="description" rows=20 cols=60>
</textarea><br>
</p>
<input type="submit" value="Submit"/>
</form>
I have a function in the views.py for saving the data in the page. But I dont know how to impliment it properly:
def save_page(request):
title = request.POST["title"]
name = request.POST["name"]
phone = request.POST["phone"]
email = request.POST["email"]
description = request.POST["description"]
Now how do I send these into the db?
And what do I put in views.py so that those data goes into the db?
so how do I open a database connection and put those into the db and save it?
should I do something like :
connection=sqlite3.connect('app.db')
cursor= connection.cursor()
.....
.....
connection.commit()
connection.close()
Thank you.
Suppose I have my models set up already.
class books(models.Model):
title = models.CharField...
ISBN = models.Integer...
What if I want to add this column to my table?
user = models.ForeignKey(User, unique=True)
How would I write the raw SQL in my database so that this column works?
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!
I've installed virtualenv and virtualenvwrapper on Windows using easy_install. But mkvirtualenv is missing. I tried to search on my machine but I couldn't find it. I don't know how to solve it. Do you have any idea?
So.. this never crossed my head before but now I just can't figure out how to do that !!
I want to verify that the object I created was really created, and return True or False according to that :
obj = object(name='plop')
try:
obj.save()
return True
except ???:
return False
Any idea ?
Cheers,

class a(object):
c=b()# how to call the b method

def __init__(self):

how to call the 'b' method not in the __init__
thanks
the error is :

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
def common_elements(list1, list2):
"""

for element in list1:

Got that so far, but can't seem to get it to work! Thanks
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
Using the pysnmp framework i get some values doing a snmp walk. Unfortunately for the oid
1.3.6.1.21.69.1.5.8.1.2 (DOCS-CABLE-DEVICE-MIB)
i get a weird result which i cant correctly print here since it contains ascii chars like BEL ACK
When doing a repr i get:
OctetString('\x07\xd8\t\x17\x03\x184\x00')
But the output should look like:
2008-9-23,3:24:52.0
the format is called "DateAndTime". How can i translate the OctetString output to a "human readable" date/time ?
I am trying to add a feature to my app that would allow me to enable/disable the "Call Me" button based on whether or not I am at [home|the office]. I created a model in the database called setting, it looks like this:
class setting(models.Model):
key = models.CharField(max_length=200)
value = models.CharField(max_length=200)
Pretty simple. There is currently one row, available, the value of it is the string True. I want to be able to transparently pass variables to the templates like this:
{% if available %}
<!-- Display button -->
{% else %}
<!-- Display grayed out button -->
{% endif %}
Now, I could add logic to every view that would check the database, and pass the variable to the template, but I am trying to stay DRY.
What is the best way to do this?
UPDATE
I created a context processor, and added it's path to the TEMPLATE_CONTEXT_PROCESSORS, but it is not being passed to the template
def available(request):
available = Setting.objects.get(key="available")
if open.value == "True":
return {"available":True}
else:
return {}
UPDATE TWO
If you are using the shortcut render_to_response, you need to pass an instance of RequestContext to the function.
from the django documentation:
If you're using Django's render_to_response() shortcut to populate a template with the contents of a dictionary, your template will be passed a Context instance by default (not a RequestContext). To use a RequestContext in your template rendering, pass an optional third argument to render_to_response(): a RequestContext instance. Your code might look like this:
def some_view(request):
# ...
return render_to_response('my_template.html',
my_data_dictionary,
context_instance=RequestContext(request))
Many thanks for all the help!
I am performing a least squares regression as below (univariate). I would like to express the significance of the result in terms of R^2. Numpy returns a value of unscaled residual, what would be a sensible way of normalizing this.
field_clean,back_clean = rid_zeros(backscatter,field_data)
num_vals = len(field_clean)
x = field_clean[:,row:row+1]
y = 10*log10(back_clean)
A = hstack([x, ones((num_vals,1))])
soln = lstsq(A, y )
m, c = soln [0]
residues = soln [1]
print residues
Many of my view functions do similar things. For the most part, they reverse to a different views upon clicking a button / a text link.
So I wrote a helper function render_reverse
def render_reverse(f, args): # args are all string type
return eval('reverse(' + f + ', ' + args + ')' )
eval is a bad practice, and is pretty slow. It takes 3 seconds to start redirecting, whereas calling reverse directly takes less than 1 second to start redirecting.
What alternative do I have? By the way, the function above doesn't work properly. I was modelling after this line (which works)
eval('reverse("homepage", args=["abcdefg"])')
Thanks.
Is it possible to use a back reference to specify the number of replications in a regular expression?
foo= 'ADCKAL+2AG.+2AG.+2AG.+2AGGG+.+G+3AGGa4.'
The substrings that start with '+[0-9]' followed by '[A-z]{n}.' need to be replaced with simply '+' where the variable n is the digit from earlier in the substring. Can that n be back referenced? For example (doesn't work) '+([0-9])[A-z]{/1}.' is the pattern I want replaced with "+" (that last dot can be any character and represents a quality score) so that foo should come out to ADCKAL++++G.G+.
foo = 'ADCKAL+2AG.+2AG.+2AG.+2AGGG^+.+G+3AGGa4.'
indelpatt = re.compile('\+([0-9])')
while indelpatt.search(foo):
indelsize=int(indelpatt.search(foo).group(1))
new_regex = '\+%s[ACGTNacgtn]{%s}.' % (indelsize,indelsize)
newpatt=re.compile(new_regex)
foo = newpatt.sub("+", foo)
I'm probably missing an easier way to parse the string.
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!
