Aug 3, 2010 · You're going to have to be a bit more specific as to how exactly you want your stuff sorted. I see the order of the elements in the inner lists stays the same, but the order of the lists themselves changes. Explain your logic. – Mar 9, 2023 · Approach #2: Using map In this method we use Python map function to iterate over the inner lists to create a list of lengths, then get the maximum with max function. Python3. def FindMaxLength (lst): maxList = max(lst, key = len) maxLength = max(map(len, lst)) return maxList, maxLength. Lists give you a way to make collections of objects in the Wolfram Language. As you will see later, lists are very important and general structures in the Wolfram Language. A list such as { 3, 5, 1 } is a collection of three objects. But in many ways, you can treat the whole list as a single object. You can, for example, do arithmetic on the Feb 25, 2015 · In case you are wondering, I am building a class that allows me to use a ulong as the indexer, and (hopefully) steps around the nasty 2GB limit of .Net by maintaining a List of Lists. public class DynamicList64 { private List> data = new List> (); private ulong capacity = 0; private const int maxnumberOfItemsPerList = Int32 Seems like a list that was compiled listlessly, probably from listening to users who were listless and wanted such a listing to be listed. Whoever the listers were, it's a good job they weren't suffering from Listeriosis or indeed were Listeria, but from the looks of it they listened to input from other lists, and a few listers were involved, which resulted in a useful list of listees. Apr 10, 2017 · The difference between stupidity and genius is that genius has its limits. Here's the code I have written thus far: Info = [ [line.strip ()] for line in Info] #Turns original list into lists of lists breaking at each new line Info_Str = str (Info) # Converts list into string to manipulate easier Info_Str = Info_Str.lower () # Converts all Nov 29, 2015 · Lists aren't very numpy anyway, so maybe a tuple of lists is good enough for you. You can get that easily and rather efficiently with an iterator expression: fiveLists = tuple([] for _ in range(5)) You can leave out the tuple if you only need it once (gives you the raw iterator). You can use this to create a numpy array if you really want to: Mar 12, 2017 · myList = [item [0].split (",") for item in myList] print (myList) OR You can enumerate to iterate through the list normally, renaming items as you go: for index, item in enumerate (myList): myList [index] = myList [index] [0].split (",") print (myList) OR You can create a new list as you iterate through with the improved value: Jul 19, 2023 · The list class is a fundamental built-in data type in Python. It has an impressive and useful set of features, allowing you to efficiently organize and manipulate heterogeneous data. Knowing how to use lists is a must-have skill for you as a Python developer. Lists have many use cases, so you’ll frequently reach for them in real-world coding. BqvN.
