Can I somehow see function parameters hint like in Visual Studio by pressing Ctrl+Shift+Space when cursor is in function call like this: someObj.doSomething("Test", "hello, wold", 4|) where | is my cursor position. Ctrl+Spase shows me that information when I start typing ...

Here is a seemingly simple problem: given a list of iterators that yield sequences of integers in ascending order, write a concise generator that yields only the integers that appear in every sequence.

I am on my personal laptop in an office with a door, so I'm not too worried abo...

I'm writing a IRC bot in Python using irclib and I'm trying to log the messages on certain channels. The issue is that some mIRC users and some Bots write using color codes. Any idea on how i could strip those parts and leave only the clear ascii text message? ...
Is there a simple way of finding out if a file is on the same filesystem as another file? The following command: import shutil shutil.move('filepatha', 'filepathb') will try and rename the file (if it's on the same filesystem), otherwise it will copy it, then unlink. I want to find out before calling this command whether it will pre...

Essentially, I have a problem that I wasn't able to reproduce consistently and I wanted some feedback on whether the proposed solution see...

Apparently some csv output implementation somewhere truncates field separators from the right on the last row and only the last row in the file when the fields are null. Example input csv, fields 'c' and 'd' are nullable: a|b|c|d 1|2|| 1|2|3|4 3|4|| 2|3 In something like the script below, how can I tell whether I am on the last line ...

Does anyone know an easier way to work with user defined types in Oracle using cx_Oracle? For example, if I have these two types: CREATE type my_type as object( component varchar2(30) ,key varchar2(100) ,value varchar2(4000)) / CREATE type my_type_tab as table of my_type / And then a procedure in package my_package as follows:...
I'm using the Python OpenCV bindings to find the contours in an Image. I'm know looking for the possibility to sort this sequence. It seems the usual python ways for list sorting don't apply here because of the linked list structure generated from OpenCV.

I'm trying to do three things. One: crawl and archive, at least daily, a predefined set of sites. Two: run overnight batch python scripts on this data (text classification). Three: expose a Django based front end to users to let them search the crawled data. I've been playing with Apache Nutch/Lucene but getting it to play nice with ...

Does anyone know of how I would, through the django ORM, produce a query that conditionally aggregated related models? Let's say, for example, that you run a site that sells stuff, and you want to know how much each employee has sold in the last seven days. It's simple enough to do this over all sales: q = Employee.objects.filter(type...
I'm using the following list comprehension: resources = [obj.get("file") for obj in iterator if obj.get("file") != None] Is there a way to "cache" the value of obj.get("file") when it's checked in the if statement so that it doesn't have to call get again on obj when it generates the return list? ...
