Sometimes, I just want to execute a function for a list of entries -- eg.: for x in wowList: installWow(x, 'installed by me') Sometimes I need this stuff for module initialization, so I don't want to have a footprint like x in global namespace. One solution would be to just use map together with lambda: map(lambda x: installWow(x,...
Consider the following code to demonstrate the question: let sequence = Seq.initInfinite (fun _ -> "Element") Seq.iter (fun _ -> printf "Element no: ?") sequence Is it in any way possible to get the current sequence number (e.g. its rank) to print? ...
Is there a jQuery way to perform iteration over an object's members, such as in: for (var member in obj) { ... } I just don't like this for sticking out from amongst my lovely jQuery notation! ...
I'm generating an unordered list through javascript (using jQuery). Each listitem must receive its own event listener for the 'click'-event. However, I'm having trouble getting the right callback attached to the right item. A (stripped) code sample might clear things up a bit: for(class_id in classes) { callback = function() { this....
So, if I try to remove elements from a Java HashSet while iterating, I get a ConcurrentModificationException. What is the best way to remove a subset of the elements from a HashSet as in the following example? Set<Integer> set = new HashSet<Integer>(); for(int i = 0; i < 10; i++) set.add(i); // Throws ConcurrentModificationExcept...
Hi, I have a simple script trying to learn about hashes in Perl. #!/usr/bin/perl my %set = ( -a => 'aaa', -b => 'bbb', -c => 'ccc', -d => 'ddd', -e => 'eee', -f => 'fff', -g => 'ggg' ); print "Iterate up to ggg...\n"; while ( my ($key, $val) = each %set ) { print "$key -> $val \n"; last if ($val e...
I'm working on an image gallery that looks up all of the images that I have uploaded, and allows me to display them 5 at a time on a single page. The problem is, i'm unsure about how to approach this. I have $_GET['max'], which is supposed to be the top most image to be displayed. $min would be $_GET['max'] - 5. In the event that the...
Hi - we are linking Iterations within TFS to an external system for tracking projects through the entire company. In the past, we were linking using the IterationPath in a TFS Project, but the problem is that people rename these IterationPaths as the projects progress, and the link is lost. So after some research, I'm thinking of doing t...
Earlier today I needed to iterate over a string 2 characters at a time for parsing a string formatted like "+c-R+D-E" (there are a few extra letters). I ended up with this, which works, but it looks ugly. I ended up commenting what it was doing because it felt non-obvious. It almost seems pythonic, but not quite. # Might not be exact...

I have a list of rows from a dataset that I need to iterate through. The problem is that the processing in the iteration may delete one or more rows from the list. Since the list is being modified, I can't use a foreach() loop. But since it is possible some of the deletions may occur at elements BEFORE the one I'm processing, I also ...
I have a list of tuples, each containing a find/replace value that I would like to apply to a string. What would be the most efficient way to do so? I will be applying this iteratively, so performance is my biggest concern. More concretely, what would the innards of processThis() look like? x = 'find1, find2, find3' y = [('find1', 'rep...
I'm trying to build a list of "phrases" using an array of word lists. I have an array that looks something like this: [ [ 'big', 'small', 'wild' ], [ 'brown', 'black', 'spotted' ], [ 'cat', 'dog' ] ] The first array is the first word in the resulting "phrase", the second array is the second word, and so on. The number of word list...
I need to create an SSIS package that will do the following: Connect to Service A and download recent activity records. These records contain an User Id and an activity code. Iterate through the results of the result set from Service A and connect to Service B retrieve additional details for each User Id (name, department, etc.). Put a...
Hi, I'm iterating over a list of tuples in Python, and am attempting to remove them if they meet certain criteria. for tup in somelist: if determine(tup): code_to_remove_tup What should I use in place of code_to_remove_tup? I can't figure out how to remove the item in this fashion. ...

It will be helpful if someone can throw some light on this. Suppose there are 4 sprints and you have decided the first sprint will go up to 10 days is it required that oth...
Lets take an example suppose we got 5 stories A,B and C,D,E. Importance Name Estimate 90 B 70 A 50 C 35 E 10 D The stories are ordered based on their importance(priority) now how you do estimate them? Is it estimated based on size of the feature? If so what does that numeric Value so for exam...
I am using ASP.MVC 1 to return an IEnumerable of objects (say, Cars): public class Car : Entity<Car> { public virtual string Make { get; set; } public virtual double Length { get; set; } public virtual string Colour { get; set; } } like this: [AcceptVerbs(HttpVerbs.Post)] public JsonResult GetRoutes() { IEnumerable<Ca...
I have a table that looks basically like this: id | redirectid | data where the redirectid is an id to another row. Basically if a row is selected, and it has a redirectid, then the redirectid data should be used in it's place. There may be multiple redirects until redirectid is NULL. Essentially these redirects form a linked list ...
I need to iterate over a queue. www.cplusplus.com says: By default, if no container class is specified for a particular queue class, the standard container class template deque is used. So can I somehow get to the queue's underlying deque and iterate over it? Thanks. ...
