i'm trying set bounds array later printed in console , summed. lower bound ($a) should less 50 , wrote code evaluate that, want re-prompt number if higher number typed. far, google , experimentation have failed me. def num_a print "pick number 1 50: " $a = integer(gets.chomp) until $a < 50 puts "um, try again please." # need here prompt response # until $a less 50 end end you restructure loop prompt , call gets both inside it: def num_a # start number doesn't meet condition = 50 # check if number meets condition yet until < 50 # ask user enter number print "pick number 1 50: " = integer(gets.chomp) # ask try again if number isn't under 50 puts "um, try again please." unless < 50 end # return entered value caller end also, i've shown in example, recommend avoiding use of global variables ( $a in case).

i trying parameter validation outside of rails. def create_statement(action, ...) valid_one_of(action, ['add', 'move', 'delete']) ... end validation method: def valid_one_of(input, valid_values) return true if valid_values.include?(input) raise "#{input} not valid value #{input.var_name}" end sample call: create_statement('bob') so output be: bob not valid value action the problem how input.var_name ? i workaround pass valid_one_of(action, ['add', 'move', 'delete'], 'action') (and use 3rd parm output) doesn't seem feels bit redundant. if not possible access variable name there more dry coding style workaround? i don't know of way name of local variable, , if could, name want? name of parameter define on method definition? name of variable in caller? i don't think "work-around" horrible, suggest couple of slight variations might read littl...

i'm trying build descending graph in cytoscape. i've got majority done quite well, i'm stuck on edge types. i'd use 'segments' curve-style, edges have points. however, instead of being zig-zags, edges constrained horizontal/vertical lines. my graph pretty constrained , user cannot manipulate positions. edges start @ 'parent' element, go straight down set amount, hit point, turn, head horizontally same x child, straight down child element. right now, lines go straight, , can add segments easily, aren't constrained , based on percentages won't have access without doing bunch of math, guess isn't terrible. current: desired: if want specific absolute positions on segments edges, you'll need convert absolute co-ordinates relative co-ordinates specify segments edges. if want different type of edges usecase, feel free propose in issue tracker.

i have oracle table called: col_mapping column in table has column values of columns table. example data of table: col_mapping id descr col_vals ------------------------------ 1 label col_1 2 name_addr col_2:col_3 3 salary col4 based on above table, go through each record in col_mapping , use col_vals part of condition in table called other_tab , i.e.: select 'y' other_tab col_1 = 'whatever1'; select 'y' other_tab (col_2 = 'whatever2' or col_3 = 'whatever2'); , finally: select 'y' other_tab col_4 = 'whatever4'; i split out col_vals condition , there more 1 value colon separated, turn or condition above examples. any on how achieve above in oracle great. thanks. this not tested. how believe can accomplished. need 2 loops. 1 loop through table col_mapping , other loop through column col_vals each row , construct condition. something this: declare a_wh...

i have interactive web based visualization. want allow users able undo while interacting visualization. noticed people suggest writing own undo function in case might difficult (so many different things keep track of). how can save last state of entire application after each interaction? idea? thanks, you use more state-driven approach , use react + redux, sounds have existing app don't want recreate. in case, depends on data looks like. single json object? in case, clone object on , on "save" previous states. you implement database , save copy of needed data timestamps and/or version numbers allow roll back. lead lot of duplication of data. another approach keep track of events modify data, , opposite of event. basic example, add number 15 "total". if wanted undo that, subtract 15. however, works if performing operations on of data. if want apply different types of data, store event along previous value. example: change name "bob...

i making function compares 2 hashtables , want keep difference of these tables. if both contain 100 keys , 2 have been altered want new hashtable equal 2 differences. here have. lost on how (keep differences) private hashtable comparehashtables(hashtable ht1, hashtable ht2) { hashtable resultsofcompare = new hashtable(); foreach (dictionaryentry entry in ht1) { if (ht2.containskey(entry.key) && ht2.containsvalue(entry.value) == false) { //keep differences } } return resultsofcompare; } it seems want check both key , value equality. if both don't match it's considered difference. creates bit of problem because type of difference can't represented in hash table. consider following ht1: key = "bob" value = 42 ht2: key = "bob" value = 13 here key same value difference. store every difference resulting structure need able contain 2 different values same key. that...

for computer science class final, have been instructed make our own game in python. requirements: 1. needs use both “while loop” , “for x in y loop.” 2. needs use list either keep track of information or score 3. needs use function gameplay, tracking score, both. 4. display art either @ beginning, after, or in between turns. 5. can multi player or single player. 6. must carry complexity commensurate final project. anyways, decided make game similar horse in basketball. object of game find answer of math problem before time runs out. if don't, letter in horse. once letters of horse, game over. here have far: import random import time timeit import default_timer print("welcome jared's math horse game!") time.sleep(1) print("you have basic geometry , algebra problem,and brain teasers...") time.sleep(1) print("for each wrong, letter, , spell 'horse'. once letters, lose. round nearest integer!!!!!!!!...
