I'm trying to get Python to a read line from a .txt file and write the elements of the first line into a list. The elements in the file were separated with a TAB so I used split("\t") to separate the elements. Because the .txt file has a lot of elements I saved the data found in each line into a separate list (data from the first lin...

I'm new to python and haven't yet read a lot of code to verify which styles are considered 'pythonic'. As I've started to code, I've been using this pattern alot. listThatMightBeEmpty = [] for items in listThatMightBeEmpty: print "this may or may not print but the loop won't cause any errors" I assume that it would be redundant t...

I'm trying to write a function in jQuery that will split lists - or really, any element that has children - that is conscious of memory use and is general enough to be widely reusable, but I'm having trouble resolving these against one another. For the sake of argument (and to keep the code on point) let's say I'm trying to split the li...

I am playing with python and am able to get the intersection of two lists: result = set(a).intersection(b) Now if d is a list containing a and b and a third element c, is there an built-in function for finding the intersection of all the three lists inside d? So for instance, d = [[1,2,3,4], [2,3,4], [3,4,5,6,7]] then the result sh...

A previous question with the same title as mine has been posted, with (I think) the same question, but had other problems in the code. I was not able to determine if that case was identical to mine or not. Anyway, I want to replace an element within a list in a list. Code: myNestedList = [[0,0]]*4 # [[0, 0], [0, 0], [0, 0], [0, 0]] myN...

I know I can solve the following problem just by creating a custom class, but can the following be strongly typed as a List(or any other type)? var x = new object[] { new object[] { new Image(), new TextBox(), new FileUpload() }, new object[] { new Image(), new TextBox() , new FileUpload()} ...

Hello, I am trying to write a predicate that given the following list in Prolog: [[1,a,b],[2,c,d],[[3,e,f],[4,g,h],[5,i,j]],[6,k,l]] will produce the following list: [[6,k,l],[[5,i,j],[4,g,h],[3,e,f]],[2,c,d],[1,a,b]] As you can see I would like to preserve the order of the elements at the lowest level, to produce elements in the ...
Hi guys, I'm writing a list reversal program for haskell. I've got the idea for the list reversal and that has lead to the following code: myreverse list1 | list1 == [] = list1 | otherwise = (myreverse(tail list1)):(head list1) Unfortunately the above code results in the following error: Occurs check: cannot construct the...
Every example of list or set usage in Python seems to include trivial cases of integers but I have two lists of objects where the name attribute defines whether two objects instances are "the same" or not (other attributes might have different values). I can create a list that contains all items from both lists, sorted, with tmpList =...
