Finding maximum of a list of lists by sum of elements in Python
What's the idiomatic way to do maximumBy (higher order function taking a comparison function for the test), on a list of lists, where the comparison we want to make is the sum of the list, in Python? Here's a Haskell implementation and example output: > maximumBy (compare `on` sum) [[1,2,3],[4,5,6],[1,3,5]] > [4,5,6] And implementati...

Python: create a function to modify a list by reference not value
Hey all- I'm doing some performance-critical Python work and want to create a function that removes a few elements from a list if they meet certain criteria. I'd rather not create any copies of the list because it's filled with a lot of really large objects. Functionality I want to implement: def listCleanup(listOfElements): i =...
In Python, are there builtin functions for elementwise boolean operators over boolean lists?
For example, if you have n lists of bools of the same length, then elementwise boolean AND should return another list of that length that has True in those positions where all the input lists have True, and False everywhere else. It's pretty easy to write, i just would prefer to use a builtin if one exists (for the sake of standardizati...
Getting the indices of all non-None items from a sub-list in Python?
As per the title, I have a nested lists like so (the nested list is a fixed length): # ID, Name, Value list1 = [[ 1, "foo", 10], [ 2, "bar", None], [ 3, "fizz", 57], [ 4, "buzz", None]] I'd like to return a list (the number of items equal to the length of a sub-list from list1), where the sub-...

Convert a sequence of sequences to a dictionary and vice-versa
One way to manually persist a dictionary to a database is to flatten it into a sequence of sequences and pass the sequence as an argument to cursor.executemany(). The opposite is also useful, i.e. reading rows from a database and turning them into dictionaries for later use. What's the best way to go from myseq to mydict and from mydic...

Probability algorithm: Finding probable correct item in a list (e.g John, John, Jon)
Hi, Take for example the list (L): John, John, John, John, Jon We are to presume one item is to be correct (e.g. John in this case), and give a probability it is correct. First (and good!) attempt: MostFrequentItem(L).Count / L.Count (e.g. 4/5 or 80% likelihood) But consider the cases: John, John, Jon, Jonny John, John, Jon, Jon I w...
Java: iterating through list of lists?
The question but in C#. So does Java have C#'s command? I need it for Matches-SearchTerm-Files-relationship. foreach(var i in BunchOfItems.SelectMany(k => k.Items)) {} [Why not for-loops?] I have done such structures in nested for loops but they soon become bloated. So I prefer something more succint like the above. public static Sta...
