is there simple way splice list of date objects: spliced = sorteddates[startdate:enddate] print spliced or requires enumeration? example : sorteddates = [july 1 2012, july 2 2012, july 3 2012, july 4, 2012] spliced = sorteddates[july 2 2012:july 4 2012] assuming have list sorteddates contains datetime object, , 2 datetime mind , maxd objects define boundaries: filtered = [d d in sorteddates if mind < d < maxd] or, more efficient since takes advantage of sorted nature of list use binary search: from bisect import bisect_left, bisect_right filtered = sorteddates[bisect_right(sorteddates, mind):bisect_left(sorteddates, maxd)]

here have problem multiple listview controls on tab2 control. in gui, have tab2 control 3 of tabs each have 1 listview control. my problem when use lv_gettext() , can't find way of distinguishing listview fetch from. to compound problem, there no way lv_add() distinguish between listviews either. normally, have distinguish between gui windows mygui:default there doesn't appear option listview controls. how can this? actually, there way specify listview. it mentions in docs, too. basically, change default listview. can't direct functions particular listview, if change default listview, can operate on it. once changed, subsequent commands operate on new default. you change this: gui, listview, listviewname or this, if need distinguish between gui windows: gui, 3:listview, listviewname here sample. paste script file , run see work. basic methodology #singleinstance,force gosub, showgui return showgui: gui, mainui:new, ...

the wikipedia summary of kosaraju-sharir algorithm follows: let g directed graph , s empty stack. while s not contain vertices. choose arbitrary vertex v not in s. perform depth-first search starting @ v. each time depth-first search finishes expanding vertex u, push u onto s. reverse directions of arcs obtain transpose graph. while s nonempty: pop top vertex v s. perform depth-first search starting @ v in transpose graph. the set of visited vertices give connected component containing v; record , remove these vertices graph g , stack s. equivalently, breadth-first search (bfs) can used instead of depth-first search. but in textbook - sedgewick's algorithms (fourth edition) - describes steps of algorithm follows: given digraph g, compute reverse post-order of reverse digraph. g r run standard dfs on g, consider unmarked vertices in order computed instead of standard numerial order the set of vertices... th...

the problem: i have items have weights. higher weight, greater chance have item go first. need have clean, simple way of doing based on core java (no 3rd party libs, jars, etc.). i've done 2 items, summing weights randomly pick number using math.random() within range. simple. items greater 2, can either more samples in same range chancing misses, or can recompute sum of weights of remaining items , select again (recursive approach). think there might out there can can faster/cleaner. code used on , over, i'm looking effective solution. in essence, randomized weight permutations. some examples: a has weight of 1, b has weight of 99. if ran simulation this, expect ba 99% of time , ab 1% of time. a has weight of 10, b has weight of 10, , c has weight of 80. if ran simulations this, expect c first item in ordering 80% of time, in cases, a , b have equal chance of being next character. any or pointers in right direction appreciated. extra details: fo...
