Hi, is there any way, in Python, to have access to an e-mail account (I'll need this for gmail but better if any works) and be able to see the number of messages in the inbox (maybe even unread messages only)?
Thank you.
Hello,
Recently I needed to generate a huge HTML page containing a report with several thousand row table. And, obviously, I did not want to build the whole HTML (or the underlying tree) in memory. As result, I built the page with the old good string interpolation, but I do not like the solution.
Thus, I wonder whether there are Python templating engines that can yield resulting page content by parts.
I am trying to create my own class of dictionary in python 3 which has a field of dict variable and setitem and getitem methods. Though, it doesnt work for some reason. Tried to look around but couldn't find the answer.
class myDictionary:
def __init(self):
self.myDic={}
def __setitem__(self, key, value):
self.myDic[key]=value
I'm getting:
'myDictionary' object has no attribute 'myDic'
Any ideas? :)
I'm cocking this up and it should be really simple but the value of sortdate is none (note im only doing this because converting a string to a date in Python is a bugger).
DateToPass = str(self.request.get('startdate'))
mybreak.startdate = DateToPass
faf = DateToPass.split('-')
sortdate = str(faf[2] + faf[1] + faf[0])
That should work? but its just being stored as null though the datetopass is being stored fine.
How would I download files (video) with Python using wget and save them locally? There will be a bunch of files, so how do I know that one file is downloaded so as to automatically start downloding another one?
Thanks.
Hi,
I'm trying to send a Python list in to client side (encoded as JSON), this is the code snippet which I have written:
array_to_js = [vld_id, vld_error, False]
array_to_js[2] = True
jsonValidateReturn = simplejson.dumps(array_to_js)
return HttpResponse(jsonValidateReturn, mimetype='application/json')
So my question is how to access it form client side, can I access it like this:
jsonValidateReturn[0]
or how I assign a name to the returned JSON array in order to access it?
I'd like to grab daily sunrise/sunset times from here. Is it possible to scrape web content with Python? what are the modules used? Is there any tutorial available?

Hi all
I have the following 4 arrays ( grouped in 2 groups ) that I would like to merge in ascending order by the keys array.
I can use also dictionaries as structure if it is easier.
Has python any command or something to make this quickly possible?
Regards
MN
# group 1
[7, 2, 3, 5] #keys
[10,11,12,26] #values
[0, 4] #keys
[20, 33] #values
# I would like to have
[ 0, 2, 3, 4, 5, 7 ] # ordered keys
[20, 11,12,33,26,33] # associated values

Hi,
I want to create a dynamic object (inside another object) in python and then add attributes to it.
I tried:

obj.a = object()
setattr(obj.a, 'somefield', 'somevalue')

Any ideas?

To learn from good examples, what are the best open source Google App Engine applications out there?
I don't care if it is Java or Python based.
Please one app per answer. Feel free to add a link to the live app (if there is) and to the project page.
Can anyone point me to some documentation on how to write scripts in Python (or Perl or any other Linux friendly script language) that generate C++ code from XML or py files from the command line. I'd like to be able to write up some xml files and then run a shell command that reads these files and generates .h files with fully inlined functions, e.g. streaming operators, constructors, etc.
I've been hunting around for a Python CouchDB tutorial and haven't been able to find anything very thorough. The only thing I've really found is this site, which I haven't gotten to work because I keep getting a 'connection refused' error when I try to create a database.
Does anyone know where I would look for a tutorial to help me with this?
I am looking for a GUI python module that is best suited for the following job:
I am trying to plot a graph with many columns (perhaps hundreds), each column representing an individual. The user should be able to drag the columns around and drop them onto different columns to switch the two. Also, there are going to be additional dots drawn on the columns and by hovering over those dots, the user should see the values corresponding to those dots. What is the best way to approach this?
What is the most straightforward way of making dictionary or list from a string in Python? Let's say I have string "{ 'x' : 3, 'y' : 4 }" and I want to parse it to a real dictionary object.
I am trying to host some files/rails app in the port 8080 for external access. For python I am using the SimpleHTTPServer module, and for rails, webrick. However, both of them does not work very well. I don't get the response back, and, sometimes, if I get it, it's VERY slow. Nevertheless, apache works very well on the port 8080 (i am not running them at the same time). What is going on?
Which are the most advanced frameworks and tools there are available for python for practicing Behavior Driven Development? Especially finding similar tools as rspec and mocha for ruby would be great.
What is the best way to store the cards and suits in python so that I can hold a reference to these values in another variable?
For example, if I have a list called hand (cards in players hand), how could I hold values that could refer to the names of suits and values of specific cards, and how would these names and values of suits and cards be stored?
I want to do a very simple webserver in python able to receive XML document over HTTP and then to send as response XML document.
Do you have any example?
just to understand How arrange the work...
many thanks!
