csv - How to display leading zeros after splitting numbers in Python -


is there way can display leading zeros after splitting numbers parts first 3 digit , last 2 digit in python 3.2? script returns numbers no leading zeros...

i have csv file looks this:

name,code blackberry,20001 wineberry,02002 rasberry,30000 blueberry,03010

my desired output:

name,code,code1,code2 blackberry,20001,200,01 wineberry,02002,020,02 rasberry,30000,300,00 blueberry,03010,030,10

my script:

import csv = [] open('aaa.csv','r') csvinput: open('bbb.csv', 'w') csvoutput: reader = csv.reader(csvinput,delimiter=',') writer = csv.writer(csvoutput,delimiter=",", lineterminator='\n') row = next(reader) row.append('code1') row.append('code2') all.append(row) row in reader: row.append(row[1][0:2]) row.append(row[1][-2:]) all.append(row) writer.writerows(all) print(all)

above script returns:

name,code,code1,code2 blackberry,20001,200,1 wineberry,02002,20,2 rasberry,30000,300,0 blueberry,03010,30,10

the csv.writer not convert strings numerical types, not causing error seeing.

i expect viewing csv file in excel, converts strings numbers wherever can. @ output in text editor , should see leading zeros there.

also, others have pointed out first slice should row[1][0:3].

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
