2 dimensional array insertion in php python equivalent -


i have little experience in php , have convert php script python. couldn't understand these lines in code:

$vars = array(); $vars['a'] = array(); $vars['b'] = array(); $vars['b'][] =  'text1';

what last line stand for? , happen if add line below code? 

$vars['b'][] =  'text2';

i appreciate on converting python. lot,

if convert php code snippet python, closest can 

>>> var = {} >>> var['a'] = {} >>> var['b'] = {} >>> var['b'][len(var['b'] )] = 'text1' >>> var['b'][len(var['b'] )] = 'text2' >>> var {'a': {}, 'b': {0: 'text1', 1: 'text2'}}

another variation

>>> class array(dict):     def __getitem__(self, key):         return dict.__getitem__(self, key)     def __setitem__(self, key, value):         if key == slice(none, none, none):             dict.__setitem__(self, self.__len__(), value)         else:             dict.__setitem__(self, key, value)   >>> var = array() >>> var['a'] = array() >>> var['b'] = array() >>> var['b'][:] = 'text1' >>> var['b'][:] = 'text2' >>> var {'a': {}, 'b': {0: 'text1', 1: 'text2'}}

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...

java.util.scanner - How to read and add only numbers to array from a text file -

i'm learning java , have question regarding reading file want read numbers file contains strings well. here example of file: 66.56 "3 java 3-43 5-42 2.1 1 and here coding: public class test { public static void main (string [] args){ if (0 < args.length) { file x = new file(args[0]); try{ scanner in = new scanner( new fileinputstream(x)); arraylist<double> test = new arraylist<>(); while(in.hasnext()){ if(in.hasnextdouble()){ double f=in.nextdouble(); test.add(f);} else {in.next();} } catch(ioexception e) { system.err.println("exception during reading: " + e); } } my problem add 66.56,2.1 , 1 doesn't add 3 after "3 or ignores 3-43 , 5-42 can tell me how skip strings , add doubles here? thanks all said 3 ie; "3, 3-43 , 4-42 strings either u read string , split , check number @ " , - or put in space between characters , integers. jvm after compilation tre...
