python - Unble to use strip method -

-

here's input:

vendor: seagate product: st914602ssun146g revision: 0603 serial no: 080394enwq size: 146.81gb <146810536448 bytes>

my code:

        iostat_cmd = client.executecmd('iostat -en '+disk+'|egrep \'vendor|size\'')         vendor = re.search(r'vendor:(.*)product:',iostat_cmd)         vendor = str(vendor.groups()).strip()         product = re.search(r'product:(.*)revision:',iostat_cmd)         product = str(product.groups()).strip()         revision = re.search(r'revision:(.*)serial no:',iostat_cmd)         revision = str(revision.groups()).strip()         serial = re.search(r'serial no:(.*)',iostat_cmd)         serial = str(serial.groups()).strip()         size = re.search(r'size:(.*)<.*>',iostat_cmd)         size = str(size.groups()).strip()

the problem is, it's not converting result of groups() string, why strip() doesn't anything. want remove leading , trailing whitespaces. please not suggest using replace because of match groups can made multiple words (for example, product name can virtual disk) , take account fact use of whitespaces/delimiters in iostat command output arbitrary, why i'm going through trouble in first place.

here's happens:

jvm 2    | <type 'org.python.modules.sre.matchobject'> jvm 2    | <type 'str'> jvm 2    | (u' seagate  ',) jvm 2    | (u' st914602ssun146g ',) jvm 2    | (u' 0603 ',) jvm 2    | (u' 080394ec41 \r',) jvm 2    | (u' 146.81gb ',) jvm 2    | (u' seagate  ',)(u' st914602ssun146g ',)(u' 0603 ',)(u' 080394ec41 \r',)(u' 146.81gb ',)

when use .groups() on match object tuple contents of captured groups regex.

to contents of first capture use .group(1) instead.

-
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 $row): ?> <div id="<?=$...
