python - iterate over a list with some conditions -


i have 2 lists, valid , locations. valid contains ids represented string numbers, , location contains id + strings (path) belonging id follow.

my goal check if id part of valid group. if true valid id , following items call functions. when inavlid id detected should skip , move item next id.

my code goes this:

valid = ['1', '2', '3', '4', '5', '6', '27', '28', '29'] locationlist = ['1', '1_path1','1_path2','1_path3','2', '2_path1','2_path2','2_path3', '55','55_path1','55_path2', '3', '3_path1' ] item in locationlist: if len(item)< 3: if item in valid: print "###########lib id found in item %s############" %item print "call bring file name function - %s" %item continue else: continue print "call fix path function - %s" %item print "call search file function -%s" %item

my probelm after else: statment item value '55' == invalid. @ point wish move item forward in list place value next id (in case '3').

my current output is:

###########lib id found in item 1############ call bring file name function - 1 call fix path function - 1_path1 call search file function -1_path1 call fix path function - 1_path2 call search file function -1_path2 call fix path function - 1_path3 call search file function -1_path3 ###########lib id found in item 2############ call bring file name function - 2 call fix path function - 2_path1 call search file function -2_path1 call fix path function - 2_path2 call search file function -2_path2 call fix path function - 2_path3 call search file function -2_path3 call fix path function - 55_path1 call search file function -55_path1 call fix path function - 55_path2 call search file function -55_path2 ###########lib id found in item 3############ call bring file name function - 3 call fix path function - 3_path1 call search file function -3_path1

i wish :

###########lib id found in item 1############ call bring file name function - 1 call fix path function - 1_path1 call search file function -1_path1 call fix path function - 1_path2 call search file function -1_path2 call fix path function - 1_path3 call search file function -1_path3 ###########lib id found in item 2############ call bring file name function - 2 call fix path function - 2_path1 call search file function -2_path1 call fix path function - 2_path2 call search file function -2_path2 call fix path function - 2_path3 call search file function -2_path3 ###########lib id found in item 3############ call bring file name function - 3 call fix path function - 3_path1 call search file function -3_path1

instead of changing data structures (although changing valid set idea):

valid = ['1', '2', '3', '4', '5', '6', '27', '28', '29'] locationlist = ['1', '1_path1','1_path2','1_path3','2', '2_path1','2_path2','2_path3', '55','55_path1','55_path2', '3', '3_path1' ] accept = false item in locationlist: if len(item) < 3: accept = item in valid if accept: print "###########lib id found in item %s############" % item print "call bring file name function - %s" % item elif accept: print "call fix path function - %s" % item print "call search file function -%s" % item

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

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
