I’m creating “Boggle” in python, and I have a list of tuples that represent coordinates on a game board: I’m trying to create a new list of lists of tuples that will represent all possible paths on the board. It’d look something like this: I tried using itertools.combinations and itertools.permutations but it doesn’t seem to do the job, for example

Tree levels in lazy Python using “Long zip with”
In this blog post about breadth-first traversal, Gibbons talks about implementing BFT with “long zip with” function Then for instance My question: My version of levels in Python is working, but my lazy version using generators is not. It’s adding an extra [] level at the end. Why? I consider this practice for using generators and laziness in Python, and
Itertools combinations, ¿How to make it faster?
I am coding this program that takes 54 (num1) numbers and puts them in a list. It then takes 16 (num2) of those numbers and forms a list that contains lists of 16 numbers chosen from all the combinations possible of “num1″c”num2”. It then takes those lists and generates 4×4 arrays. The code I have works, but running 54 numbers
All combinations of a row in a dataframe
i have the following Dataframe (df = ) with around 40 mio rows. i try to have the following output: at first i thought to use itertools combinations, it.combinations(Colors[“Colors”],2), but the problem was, that it gives me the combinations of the whole column and don’t correlate to the column “No”. The next try was to aggregate the whole dataframe to
How to generate itertools.product with a “sum” condition?
My code is: My result is: “[….., (0, 0, 0, 19), (0, 0, 0, 20), (0, 0, 0, 21), (0, 0, 1, 0), (0, 0, 1, 1), (0, 0, 1, 2), (0, 0, 1, 3), (0, 0, 1, 4), ….., (0, 0, 1, 16), (0, 0, 1, 17), (0, 0, 1, 18), (0, 0, 1, 19), (0, 0, 1, 20),….]”
How does Python hash itertools.count()?
I am trying to understand the underlying mechanics behind hash(itertools.count(x, y)). I am not used to looking deeply into CPython implementations, but I noticed that in itertoolsmodule.c the static PyTypeObject count_type has 0 for tp_hash. I am assuming that this means that it does not implement hash in C. So, how does it get taken care of? Is there a
How to improve the pattern matching on a list in Python
I have a big list, which may carry thousands to millions of entries. I set a window of finite size to slide over the list. I need to count the matched elements in the windows and repeat the procedure by sliding the window 1 position forward at a time. Here is a simple example of a list Assuming the window
Is it possible to get binary count from Counter() Python
Using Counter(), I want to do a binary count of variables in a list. So instead of getting the count for each variable, I would simply like to have a Counter() variable, in which all values are one. So for a given list: I want the output to be: Instead of: I am aware that I could loop through the
Generate all permutations including abbreviations with weightages
My string – I want to generate all permutations with the original name and abbreviations and assign weightages to each – Not concerned about this output data stucture, it can be anything. Weightage is 1 if no abbreviations and full names are used. If an abbreviation is used, the weight gets decreased by 10%. For example ARUNGINDULKAR in the 2nd
Get all possible combinations between two lists, including multiple connections
With I get the 16 possible individual combinations of the lists l1 and l2, [(1,1), (1,2), … ] etc. Is there a way to also get combinations that ‘connect’ the lists in multiple ways? For example, I could have the following combinations [(1,1), (2,3)], [(1,3), (2,4), (3,2)], and [(1,2), (2,4), (3,3), (4, 1)]. Any help would be greatly appreciated. Answer
