datetime - Why %z is not supported by python's strptime? -

- 

>>> datetime.strptime('2014-02-13 11:55:00 -0800', '%y-%m-%d %h:%m:%s %z') traceback (most recent call last):   file "<stdin>", line 1, in <module>   file "/system/library/frameworks/python.framework/versions/2.7/lib/python2.7/_strptime.py", line 317, in _strptime     (bad_directive, format)) valueerror: 'z' bad directive in format '%y-%m-%d %h:%m:%s %z'

i understand it's not supported, don't know why. seems it's not hard support that. , 'offset utc' not ambiguous timezone abbreviation.

until python 3.2, python's datetime module had no timezone() object. supported 3rd-party libraries providing timezones providing datetime.tzinfo() abstract base class, no timezone object included. without timezone object, no support parsing timezone offsets either.

as of python 3.2, z supported, because version (and up) added datetime.timezone() type:

>>> import datetime >>> datetime.datetime.strptime('2014-02-13 11:55:00 -0800', '%y-%m-%d %h:%m:%s %z') datetime.datetime(2014, 2, 13, 11, 55, tzinfo=datetime.timezone(datetime.timedelta(-1, 57600))) >>> _.tzinfo datetime.timezone(datetime.timedelta(-1, 57600))

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
