Set community index as a vertex attribute with IGraph Python -


when detect communities on graph igraph in python, result this:

print g.community_multilevel(return_levels=false)  clustering 100 elements , 4 clusters [0] 16, 17, 18, 20, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35,     36, 37, 39, 40, 44 [1] 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 19, 38, 92, 94, 96,     97, 98, 99 [2] 42, 43, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60,     61, 62, 63, 64, 66, 67, 69 [3] 21, 41, 65, 68, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83,     84, 85, 86, 87, 88, 89, 90, 91, 93, 95

i'm adding corresponding community number attribute each vertex this:

for v in g.vs():     c = 0     in g.community_multilevel(return_levels=false):         if v.index in i:             print v.index,i,c             v["group"] = c         c += 1

is there more elegant way achieve this?

what doing terribly inefficient because running community detection algorithm every single iteration of outer loop though result should same no matter how many times run it. simpler way be:

cl = g.community_multilevel(return_levels=false) g.vs["group"] = cl.membership

1111. appearing after print sequence - php -

morning, i have code takes string of shoe sizes, explodes , puts in table. code works , info displayed correctly on page after table there few 1's after table. i'm confused this. so table looks (in columns of 3 on webpage) available in following sizes: 3 4 5 6 9 10 111 here's codes, purpose of example $x = 3|4|6|10|9 function get_sizes_pipe($x) { $counter = 0; $splits = explode("|",$x); asort($splits); $x = print "<table class='greentable'>"; $x .= print "<thead><tr><th scope='col' colspan='3' abbr='starter'>available in following sizes:</th></tr></thead><tbody><tr>"; foreach ($splits $split) { $entry = print "<td>".$split."</td>"; if($counter == 2){ $entry .= print "</tr><tr>"; $counter =0; } else { $counter++; ...
