python - Convert NLTK LazySubsequence to a list -


is there nltk built-in functions convert nltk lazysubsequence list?

e.g.

from nltk.corpus import brown corpus = brown.sents() ls = corpus[0:250] print('type(corpus)[0:250]: {0}'.format(type(ls)))

returns type(corpus)[0:250]: <class 'nltk.util.lazysubsequence'>.

i know convert looping around e.g. follows convert_lazysubsequence_to_list(), wonder whether nltk offers native way cast python list:

from nltk.corpus import brown  def convert_lazysubsequence_to_list(ls):     corpus = []     s in ls:         corpus.append(s)     return corpus  corpus = brown.sents() ls = corpus[0:250] print('type(corpus)[0:250]: {0}'.format(type(ls)))  my_list = convert_lazysubsequence_to_list(ls) print('type(my_list): {0}'.format(type(my_list)))

outputs

type(corpus)[0:250]: <class 'nltk.util.lazysubsequence'> type(my_list): <type 'list'>

actually easier might think

>>> nltk.corpus import brown >>> corpus = brown.sents() >>> ls = corpus[0:250] >>> print('type(corpus)[0:250]: {0}'.format(type(ls))) type(corpus)[0:250]: <class 'nltk.util.lazysubsequence'> >>> my_list = list(ls) >>> print('type(my_list): {0}'.format(type(my_list))) type(my_list): <class 'list'>

no need special nltk functions. pythons built in list() can you.

morning, i have code takes string of shoe sizes, explodes , puts in table. code works , info displayed correctly on page after table there few 1's after table. i'm confused this. so table looks (in columns of 3 on webpage) available in following sizes: 3 4 5 6 9 10 111 here's codes, purpose of example $x = 3|4|6|10|9 function get_sizes_pipe($x) { $counter = 0; $splits = explode("|",$x); asort($splits); $x = print "<table class='greentable'>"; $x .= print "<thead><tr><th scope='col' colspan='3' abbr='starter'>available in following sizes:</th></tr></thead><tbody><tr>"; foreach ($splits $split) { $entry = print "<td>".$split."</td>"; if($counter == 2){ $entry .= print "</tr><tr>"; $counter =0; } else { $counter++; ...
