what is wrong with this code of nltk python -

- 

def ethos(file):     f = open(file)     raw = f.read()     tokens = nltk.word_tokenize(raw)     words_to_match = ['love' , 'good' , 'excellent' , 'perfect' , 'brilliant' , 'easy' , 'well' , 'made' , 'impressive' , 'great']     matching_tokens = []     tokens in tokens:         if tokens in words_to_match:             matching_tokens.append(tokens)             return matching_tokens

i not able understand why code not able return list, returning 1 token/word, after execution

your return statement in loop, means function returns tokens in words_to_match true. correct problem, move return out of loop, this: (for simplicity removed part of opening file. it's test. you'll have let method read file)

import nltk  def ethos():     raw = 'i love made products'     tokens = nltk.word_tokenize(raw)     words_to_match = ['love' , 'good' , 'excellent' , 'perfect' , 'brilliant' , 'easy' , 'well' , 'made' , 'impressive' , 'great']     matching_tokens = []     tokens in tokens:         if tokens in words_to_match:             matching_tokens.append(tokens)     return matching_tokens  print ethos()

the result is

['love', 'well', 'made']

it seems work

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