I am trying to deploy a Haskell web application calling into a Python backend spawned as a subprocess. I am pushing a single whose structure goes like this: app |– Main.hs src |– (Haskell source files) test |– (my test files) Procile — "web: <name of the haskell executable>-exe" requirements.txt — (my Python requirements) I ..
I am writing a microservice in Haskell and it seems that we’ll need to call into a Python library. I know how to create and configure a process to do that from Haskell, but my Python is rusty. Here’s the logic I am trying to implement: The Haskell application initializes by creating a persistent subprocess ..
This question is about a language which has generators (like python) vs haskell (which is natively lazy). I’m interested in: how would graph traversal look like if it were pure, lazy and async at thes same time (get_neighbors is async so everything needs to work in parallel, and not wait for a single slow node. ..
How to write this python program similarly in Haskell? I am so confused with Haskell recursive functions python code: //array should be taken while runtime for Haskell program x = [[8, 1, 0, 1, 0, 0, 0],[9, 0, 1, 1, 0, 0, 0],[23, 0, 0, 1, 0, 0, 0],[2, 0, 0, 1, 1, 0, 0],[6, ..
Imagine a trading bot with Haskell as my algorithm base and python for data analysis. It seems very hard to code API request in Haskell compared to Python. Or am I wrong. What structure should I use? I thought of querying the data in python then sending them to Haskell either through HTTP or a ..
For example you may see Python code such as xss = [[-0.104],[-0.047],[-0.046]] yss = [[0.183, 0.366, 0.456], [0.971, 0.156, 0.856]] answers = [sum([xs * y for xs, y in zip(xss, ys)]) for ys in yss] print(answers) (Here this code is taken from https://stackoverflow.com/a/63442625/13860599) Or Haskell code such as cartesian :: [[a]] -> [[a]] cartesian  ..
This is a simple python code that takes an input and matches it with a frequency array to check if it belongs to the English language or Portuguese language. strinp=input() arr=list(strinp) eng_freq = [8.12,1.49,2.71,4.32,12.02,2.30,2.03,5.92,7.31,0.10,0.69,3.98,2.61,6.95,7.68,1.82,0.11,6.02,6.28,9.10,2.88,1.11,2.09,0.17,2.11,0.07] pt_freq = [12.21, 1.01, 3.35, 4.21, 13.19, 1.07, 1.08, 1.22, 5.49, 0.30, 0.13, 3.00, 5.07, 5.02, 10.22, 3.01, 1.10, 6.73, 7.35, ..
I am used to working with Python and fairly new to Haskell. I was wondering how strings are left/right alinged in Haskell and if there exist equivalent functions to the following Python functions in Haskell: str = "Hello stackoverflow." # Printing a left aligned string print (str.ljust(40)) # Printing a right aligned string print (str.rjust(40)) ..
I have a working (albeit inefficient) function to check if a number is prime in python and I’d like to convert it to Haskell. Efficiency doesn’t matter to me right now as I am focusing primarily on making a readable algorithm in haskell that uses language features a beginner would understand. I’m new to haskell ..
How would you compare Haskell,Python,or other languages best for programming to have data inputs(as some models to be)interpreted by math formulas(mostly category theoritical and topological) and at the same time using AI for some simulations?how would the languages differ from each other. Thanks in advance Source: Python..
