This is explained in numpy's documentation. There are a few functions to create a numpy array. The starting point is here [url]http://numpy.scipy.org/#docs[/url]. Re: C++ & embedded Python , Expression Evaluator 15 Years Ago by somada141 Could you possibly direct me to any simple examples or sth? The numpy API documentation is pretty intimidating Re: C++ & embedded Python , Expression Evaluator 15 Years Ago by Gribouillis I can't help you much, because I never created a numpy array from C, but look at the collection of array creation functions at page 241... of the guide to numpy, and select the most appropriate for your needs :) Re: How to Create an Expression Evaluator in C++ 15 Years Ago by VilePlecenta [CODE]#include <iostream> using namespace std; int main() { int x = 0, Total = 0; /* You must make a varaible a, b, c to hold the value unless they are constant */ printf( "Hello.

Re: Hold'em Hand Evaluator 14 Years Ago by lrh9 The structure is admittedly confusing. I need to work on that. I had a Dealer class I forgot to include. Some code for shuffling and dealing from the deck because a deck doesn't really shuffle or deal itself. Was a poor decision that sacrificed practicality for purity. Would be easier if they were methods on the deck. How are the docstrings … Re: Hold'em Hand Evaluator 14 Years Ago by TrustyTony docstring from line 175 until 186 for example Re: Hold'em Hand Evaluator 14 Years Ago by TrustyTony Have you considered splitting code to modules? Just using [icode]return self.attr <cond> other.attr[/icode] would compact the helper class quite a bit. On the other hand I do not like the _ variable. It should be also possible to evaluate objects repr to recreate the object. Re: Hold'em Hand Evaluator 14 Years Ago by lrh9 I refactored the code and added an example. The only problem remaining as far as I know is that if two hands are of equal rank but one has higher kickers, my test code will display text suggesting that they are equal. (Differences in kickers are significant in this program though. If one hand has higher kickers than another it will be greater … Re: Hold'em Hand Evaluator 14 Years Ago by lrh9 [code=Python]# -*- coding: utf-8 -*- ##Copyright © 2010 Larry Haskins ##This program is free software: you can redistribute it and/or modify ##it under the terms of the GNU General Public License as published by ##the Free Software Foundation, either version 3 of the License, or ##(at your option) any later version. ##This program is … Re: Hold'em Hand Evaluator 14 Years Ago by lrh9 There is a small bug in my code.

I would like to mention that this code needs Python 3 to run. Re: Hold'em Hand Evaluator 14 Years Ago by lrh9 Yes. I'm coding in Python 3. If you want to propose changes, feel free. You won't be stepping on any toes. I've been collaborating with people on #python on irc.freenode.net. They've given advice and recommendations. Some I've adopted and some I've rejected.

I've been studying finite state machines and it has me thinking that some of this might be better solved using finite state machines. The basic idea is that you have a collection of cards you want to find a hand for. You can iterate over the cards and update the state of the hand as you go. When you get to the end of the …
