python - GNU Parallel to replace piping xargs -n 1 -

-

i have python script operates on list of state abbreviations single argument, , text file contains state abbreviation strings.

the normal call is...

$ mypy.py "ak"

...to run script on alaska.

i'm using following run script on each state abbreviation taken statelist.txt file:

$ cat statelist.txt | xargs -n 1 ./mypy.py

i parallelize execution, , gnu parallels looks right option. saw from here should syntax replacing xargs -n1:

$ find . -name '*.html' | parallel gzip --best

so, attempts were

$ cat statelist.txt | parallel python mypy.py

and

$ cat statelist.txt | parallel python mypy.py {}

but both of these returning:

/bin/bash: mypy.py: command not found traceback (most recent call last):   file "<stdin>", line 1, in <module> nameerror: name 'ak' not defined

it seems passing in unquoted perhaps? when add quotes '{}' passes in literal "{}".

cat statelist.txt | parallel --gnu python mypy.py

without --gnu, gnu parallel may choose emulate older tool same name (tollef's parallel). --tollef default behavior on many distros, , why otherwise valid gnu style invocation fails.

ps: chances xargs had -c or -p parallelization too.

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