I just wanted to use RC to check whether Python has a "while"-type statement and what the syntax is. I figured this would be the place to start looking. As far as I can tell, it is not. The closest I came was going through "Basic language learning" which gets me to a sub-category "control structures" in the task description of which I find a link to "loop structures" which informs me that it is a "former task" and that I should now look for "Iteration" tasks. Which, in turn, do not appear to exist, or at least not on this page or on a page linked from here. To me, at least, this all looks confused and disorganized. [[User:Sgeier|Sgeier]] 23:02, 14 September 2009 (UTC)
I think the following sub-categories would make sense in addition to the existing Control Structures category (there are probably better names for some of them):
* '''Basic Data Operations:''' Here go all the fundamental operations on basic data types.
: ''Articles:'' [[Address Operations]], [[Basic pointer and reference operations]], [[Function as an Argument]]
::Add <nowiki>{{basic data operation}}</nowiki> below <nowiki>{{task}}</nowiki> to appropriate articles. --[[User:Short Circuit|Short Circuit]] 18:09, 21 March 2007 (EDT)
* '''Data Structures:''' Anything covering data structures and how to create and read them. Only the most basic algorithms should be here.
: ''Articles:'' [[Assigning Values to an Array]], [[Classes]], [[Collections]], [[Compound Data Type]], [[Create a Sequence of unique elements]], [[Creating an Array]], [[Creating an Associative Array]], [[Data Representation - Controlling Fields in a Structure]], [[Data Representation - Getting the Size]], [[Data Representation - Specifying Minimum Size]], [[Defining Primitive Data Types]], [[Enumeration]], [[Introspection]], [[Polymorphism]], [[Retrieving an Element of an Array]], [[Singly-Linked List (element insertion)]], [[Singly-Linked List (element)]], [[String Byte Length]], [[String Character Length]], [[Table Creation]], [[Table Creation - Address]], [[Two-dimensional array where both dimensions are given at run time]]
::This category needs to be further parted out into categories representing actual structures, operations inherent to them, and possibly their representation. I did create <nowiki>{{data structure}}, though. It should be placed before {{task}}</nowiki>. --[[User:Short Circuit|Short Circuit]] 19:17, 21 March 2007 (EDT)
* '''Basic algorithms:''' For all other "pure" algorithms. Those algorithms of course often will make use of the data structures above, but then their point should not the data structure itself, but some operation of it (e.g. sorting, combining two data structures into another one, etc.).
: ''Articles:'' [[Apply a callback to an Array]], [[Bubble Sort]], [[Change string case]], [[Copy a string]], [[Creating a Hash from Two Arrays]], [[Increment numerical string]], [[IsNumeric]], [[Product of Array]], [[Regular expression matching]], [[Select from Array]], [[Sorting Using a Custom Comparator]], [[Sorting an Array of Integers]], [[Sum of Array]]
* '''Input/Output''': Everything related to I/O, serialization or the file system
: ''Articles:'' [[DOM XML Serialization]], [[File I/O]], [[Object Serialization]], [[User Input]], [[User Output]], [[Walk Directory]], [[Walk Directory Tree]], [[Zero fill]]
* '''Program execution environment:''' Everything which relates to the environment the program executes in (except that strictly speaking, File I/O also relates to the program's environment).
: ''Articles:'' [[Command Line Arguments]], [[Discover the Hostname]], [[Execute a System Command]], [[Fork Proccess]]
* '''Concurrency:'''
: ''Articles:'' [[Metered Concurrency]], [[Simple concurrent actions]], [[Synchronous Concurrency]]
* '''GUI:'''
: ''Articles:'' [[Creating a Window]]
* '''Complex algorithms and applications:'''
: ''Articles:'' [[Creating a SOAP Client]], [[SQL-Based Authentication]], [[Towers of Hanoi]], [[XML and XPath]]

I think this page should be entitled "Solutions by Programming Category", because the list is by category, rather than by task.
Would it make sense to combine many of those file-system kinda things into a single task? In many languages, testing for the existence, readability and size of a file uses effectively the same mechanism/s (E.G. in TCL it would be "file exists $fname" and "file readable $fname" and "file size $fname" etc). I'm not sure it really warrants a "category" if most(?) languages will deliver the answers to all these questions by invocation of the same underlying mechanism. (In IDL you'd call result=file_info(fname) and the result is a structure with elements "result.exists" and "results.read" and "result.size" and so forth; thus all of these are the same task and you simply look at a different elements in the returned structure).

It might also be useful to add a tasks by category link to this page in the left hand main menu of rosetta code.
:Well, instead of regrouping, another idea would be to make a "bigger" task which would re-use all the other codes. If I understand what you're saying, you want to make a page which would list almost *everything* you can do with say, file interaction. Would you mind creating a post on the Village Pump to discuss this ? --[[User:CrashandDie|CrashandDie]] 01:16, 5 October 2007 (MDT)

I think this category is getting a bit big. Maybe it could be divided up more than it is now. [[:Category:Programming Tasks]] can still be a big pile, but this category could be divided. We need some suggestions for new groups, though. Once we have lots of subgroup ideas we can start getting to wiki-work. What do you guys think? --[[User:Mwn3d|Mwn3d]] 03:12, 10 August 2008 (UTC)

Kinda messy

I just wanted to use RC to check whether Python has a "while"-type statement and what the syntax is. I figured this would be the place to start looking. As far as I can tell, it is not. The closest I came was going through "Basic language learning" which gets me to a sub-category "control structures" in the task description of which I find a link to "loop structures" which informs me that it is a "former task" and that I should now look for "Iteration" tasks. Which, in turn, do not appear to exist, or at least not on this page or on a page linked from here. To me, at least, this all looks confused and disorganized. Sgeier 23:02, 14 September 2009 (UTC)

Nothing is perfect, but my path was: Basic Language Learning → Iteration → Loop/While. While, for and so on are "control structures", but first they are iterations; so the old path gave you to Flow Control Structures, which points to Loop Structures, which was the page holding loop structures in general, it is kept since some iterations still might be uncategorized (if you look at Iteration, you see Loop/While, Loop/For and similar... not all Loop Structures fit those categories) or code still need to be moved.
