Hello StackOverflow, I have problems with writing an specific application in a scala-esque and elegant way. I tried this for some time now, but I cannot find a "good" solution to this Problem: Given that I have the following List: List("foo", "bar", "baz", "blah") I want to Iterate over this list, not only giving me the current elem...
I have a list of 16 elements [a00,a01,a02,...,a15] and would like to compute a list [b0,b1,b2,b3,b4,b5,b6,b7] where b0 = a00*256+a01 b1 = a02*256+a03 b2 = a04*256+a05 (etc.) what's the easiest way of doing this? (I'm a beginner in python) ...

In the following snippet my intention is to convert a System.Object (which could be an FSharpList) to a list of whatever generic type it is holding. match o with | :? list<_> -> addChildList(o :?> list<_>) | _ -> addChild(o) Unfortunately only list<obj> is ever matched as a list. I would ...
On our website http://www.dimagi.com, the items in the jQuery menu near the top of the screen gain a background-color on hover. The hover background-color of the rightmost list item ("About Us") is cut off at the very right edge of the text, seemingly only in WebKit (tested Safari and Chrome in Windows XP). Can anybody see what I might...
I have a list in python and I'd like to iterate through it, and selectively construct a list that contains all the elements except the current k'th element. one way I can do it is this: l = [('a', 1), ('b', 2), ('c', 3)] for num, elt in enumerate(l): # construct list without current element l_without_num = copy.deepcopy(l) l_witho...
Given a generic List I would need some kind of index (in the database sense) that would allow me fast retrieval. The keys for this index would not be unique, so I can't use a dictionary. Here's what I have in mind: Given a class Foo { P1, P2, P3 } that may have data like this { "aaa", 111, "yes" } { "aaa", 112, "no" } { "bbb", 111, "no"...

I want to be able to switch the array to a list and then be able to show what is selected out of the list by the parameter the user selects. Can someone help please?? :) ...
I think list comprehensions may give me this, but I'm not sure: any elegant solutions in Python (2.6) in general for selecting unique objects in a list and providing a count? (I've defined an __eq__ to define uniqueness on my object definition). So in RDBMS-land, something like this: CREATE TABLE x(n NUMBER(1)); INSERT INTO x VALUES(1...
I need to traverse a LinkedList a number of times, in a way that suggests using ListIterator. Is there a way to reset a ListIterator? or is it better to just create a new one? (and what if I can't because I don't have access to the list?) edit: and is there a way to create a ListIterator that points to the end of the list? (so that has...
What is the most efficient way to shift a list in python? Right now I have something like this: >>> shift = lambda l, n: l[n:]+l[:n] >>> l = [1,2,3] >>> shift(l,1) [2, 3, 1] >>> shift(l,2) [3, 1, 2] >>> shift(l,0) [1, 2, 3] Is there a better way? ...
When you want to add some extra information into a class, what way would you prefer: would you extend that class or make a wrapper around it? In my particular scenario, I want to add some pagination information with a List that I get from database. That pagination information will include: int currentPage; int totalResults; int contain...
Here's my specific predicament: I have a custom List Display Form that I am editing in SharePoint designer. It has the standard field editing form, and a Web part zone with a custom list Web part in it. When a user comes to this page, they're arriving here from clicking on an existing item in a list, we'll call it the "Site List." Each ...
Hi all, Doing some XML processing in python. (Edit: I'm forced to use Python 2.4 for this project, boo!) I want to know what is the most Pythonic way to do this (create union of all values in multiple lists): def getUniqueAttributeValues(xml_attribute_nodes): # split attribute values by whitespace into lists result_lists=lis...
What is the best friend-list table design (for performance)? Probably there should not be many rows for every frienship. What Facebook and Myspace is doing? (in MySQL) ...

I'd like to identify groups of continuous numbers in a list, so that: myfunc([2, 3, 4, 5, 12, 13, 14, 15, 16, 17, 20]) returns: [(2,5), (12,17), 20] And was wondering what the best way to do this was (particularly if there's something inbuilt into Python). Edit: Note I originally forgot to mention that individual numbers should be...
Hey, I am looking for a linked list and related algorithms implementation for Python. Everyone I ask just recommends using built in Python lists, but performance measurements indicate that list insertion and removal is a bottleneck for our application. It's trivial to implement a simple linked list, but I wonder if there is a mature lib...
