python - Reasons to rename property to _property -


i reading source code of collections.py yesterday.

in namedtuple function, template string generated , execed in temporary namespace.

in namespace dict, property renamed _property , tuple _tuple.

i wonder what's reason behind this. problems renaming helps avoid?

in general, underscore names used in standard library to keep namespace clean.

in case of _tuple, necessary because you're allowed use "tuple" field name:

>>> example = namedtuple('example', ['list', 'tuple', 'property']) >>> e.list [10, 20, 30] >>> e.tuple (40, 50, 60) >>> e.property 'boardwalk'

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
