|NEsted Lists assign values directly (without .append), how to initialize and how to best organize such lists of lists|
| by Josh Freed in Programming Languages|
Let me first elaborate a little on the background and then pose my
question. I want to write a script to plot my data. It should search files
I specify load the data from them, do some postprocessing like
normalisation averaging and timestamp extraction, store them in an array or
list of lists of some sort (or a database but im not too familiar with
sqlite) and then plot data i specify.
|Recursively remove spaces in a list (of lists of lists of lists…) in python|
| by JoeKaras in Coding|
I'm trying to remove all of the spaces from elements in a list of lists
(potentially of lists of lists etc. etc.)
The module I've
written returns the first appearance of a base case alone instead of the
whole recursed object, if that makes sense. Any idea what I've done

|How do I convert a nested tuple of tuples and lists to lists of lists in Python?|

I have a tuple containing lists and more tuples. I need to convert it

|Assigning values to lists within lists within lists within lists|
| by Megatomic in Programming Languages|
I have a hierarchy of lists within lists, and at the very bottom I'm
assigning a decimal value. I need to assign this value based on the
combination of the lists that are above it in the hierarchy. Each element
of a particular list is an Enum value, so one combination could be Trees,
Buildings, BuildingNumber. And another Trees, Buildings, BuildingPrice.
What would be the best way of assign
|Identifying lists that have 3 elements in common in a lists of lists|
| by Dirigible in Programming Languages|
I have a list of lists. If there are subslists that have
the first three elements in common , merge them into one list and add all
the fourth elements.
The problem is best explained in code and
the required output.
a_list = [['apple', 50, 60, 7],
['orange', 70, 50, 8],
['apple', 50, 60, 12]]
|How can I have a list of lists, with the top-level li's being inline, and the lower-level lists being normal lists?|
| by Stjepan in Web Design|
Hey so I have a list, with some of the items containing other lists. The
first level of lists needs to be inline, but any list a level down should
be normal list-item. It works better if I show you. This is what I

|Pythonic way of summing lists and lists of lists|
| by deanschang in Development Tools & Services|
I'm trying to find a neat way of summing a list and a list of lists in
the same function, so far I've got:
Fails late for item = ['a', 'b']
return sum(item) == sum(range(1,
sum(reduce(operator.add, item)) == sum(range(1, 10))
|JQuery How to limit the number of items in sortable linked lists - connect lists|
| by ti22 in Development Tools & Services|
I want to limit the number of images I can drag into each list. Each
time the user will drag a clone into one of the connected lists. I need to
limit the number of items they can drop into the sortable lists.
Do I need a custom Stop function? I tried that but it only limited the
specific image rather than all of the images. What else can I do?
How can I do this?
|How do I loop through two lists of lists and avoid duplicate combinations for values at specific positions?|
| by neosephiroth86 in Programming Languages|
I would like to loop through two lists of lists and avoid duplicate
combinations of values between positions 1 and 2 of each list.
a = [[2007, 206, 205, 8], [2007, 206, 208, 9]]
b = [[2007,
205, 206, 8], [2007, 207, 210, 10]]
In this case for
a, positions 1 and 2 would be 206 and 205 respectively, and for b,
positions 1 and 2 would be 205 and 206.
|Is there a typical name for a function like 'map' that operates on a list of argument lists instead of multiple lists of arguments?|
| by odunthorne in Development Tools & Services|
(I finally posted and accepted an answer to the effect of "no, there
isn't, and the question isn't actually that general".)
the Common Lisp function 'mapcar'. It takes a function and some lists as
arguments, and calls the function with arguments pulled from the same
position in each list.
Do standard libraries typically have a
similar function that takes a singl
