a simplified version of problem: want write method in python takes in 1 parameter, either list of strings or custom object holds list of strings. return size of list. method user call want simple user (essentially don't want 2 methods doing same exact thing except single line of code , don't want import non python standard libraries) i realize overloading not possible in python in java. what way go this/what standard way? solutions have thought of are: write 2 different methods. write 1 method 2 parameters , defaults, check defaults move accordingly. write 1 method 1 parameter, check kind of object passed in, move accordingly (not entirely sure if type checking possible) from design perspective if statements each type of object want handle not seem great in long run, don't see other solutions (besides separate methods) thank suggestions! in python, use single dispatch function establish single method different implementations based on argument type (...

i'm having trouble figuring out how deal inventory text based java game. finished data structures , algorithms, figured project resume. currently, create inventory in constructor of player class. instantiate inventory 3 potion items, item class. try in player constructor, can't figure out why not working. my question is, how should go instantiating every character 3 potions in his/her inventory? player class: package projectmoria; import java.util.arraylist; import java.util.list; public class player { private final string name; private final string description; private final int maxhitpoints; private int hitpoints; private final int mindamage; private final int maxdamage; private final int defense; private double critchance; private int currx; private int curry; private room currroom; private list<item> inventory; public player(string name, string description, int maxhitpoints, int m...

solution: solved using regex provided gary_w below , simple powershell command uses discussed replacement function. there no need use built in regex activity in software use. here´s ps: "100,000.00" -replace "([,.]\d{2}$)|[,.]","" regular expressions freaking me out. cannot used logic. however, think current re problem quite simple 1 bur cannot make work :( so here´s want achieve: want re match digits before last 2 decimal places. thus, re must ignore "." , "," , last 2 digits. > examples: > 1.000.000,00 --> 1000000 > 123,456.00 --> 123456 > 100.000,00 --> 100000 > 10.000,00 --> 10000 > 10,000.00 --> 10000 > 1.000,00 --> 1000 > 100,00 --> 100 > 99.88 --> 99 > 99,88 --> 99 > 1,23 --> 1 > ... any ideas how working? here's how in oracle, it's worth. maybe regex used here give idea. read regex "look match of comma or decimal followed 2...

the goal add new rules existing session. can accomplished using kiescanner, update kiecontainer higher version based on "kjar" , update session without need create new 1 , re-establish fact base. now question how 1 create kjars , add these local maven repository artifacts resolvable , accessible kiescanner. the examples in official drools repo sadly of no geared towards own needs , of greater complexity. nothing found on topic , not documentation provides details or gives more information mentioning should possible without providing concrete example. so how working , still compact/general example use of drools kiescanner including creation , adding of kjars like?

i'm working on little program draw stacking cups using paint method controlled nested loops. have working, except when outer while loops finishes, drawing erases. the program consists of 2 while loops. first incrementing row of drawing , second draws cups in row. watching program in debug mode, after final execution of outer while loop, outer while statement evaluated (while (baselength > 0) false, program goes line int counter2 = 0, drawing disappears , program exits. i tried building loops instead of while, , same effect. once outer loop evaluated false, drawing disappears. it seems paint(g) method don't quite understand that's causing drawing erase. ideas? import javax.swing.jframe; import java.awt.graphics; import java.awt.color; public class cups1 extends jframe { /* * declaring instance variables. startx , starty represent top left coordinates * of first cup block in bottom row. cupwidth , cupheight represent width * , height of e...

trying write list comprehension can iterate through string input() , create list each character of string having it's own index. in essence, want function this: x = ["00.00"[h] h in range(len("00.00"))] print(x) > ['0', '0', '.', '0', '0'] when putting actual string ("00.00") in there, python want do. refuses take input() same way: >>> x = [input()[h] h in range(len(input()))] > traceback (most recent call last): file "<stdin>", line 1, in <module> file "<stdin>", line 1, in <listcomp> indexerror: string index out of range the word "what" in there inputted, same else i've put in. i'm not sure what's different input() changes how indexes work. it? you produced rather long-winded spelling of list() . there no need use list comprehension here: list(input()) what goes wrong expression @ front of list compr...
