Profiling Python via C-api (How to ? ) -


i have used python's c-api call python code in c code , want profile python code bottlenecks. came across pyeval_setprofile api , not sure how use it. need write own profiling function?

i thankful if can provide example or point me example.

if need know amount of time spent in python code, , not (for example), in python code time spent, python profiling tools not want. write simple c code sampled time before , after python interpreter invocation, , use that. or, c-level profiling tools measure python interpreter c function call.

if need profile within python code, wouldn't recommend writing own profile function. provide raw data, you'd still have aggregate , analyze it. instead, write python wrapper around python code invokes cprofile module capture data can examine.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
