Good friend of mine heard about my attempt to create compact, simple Python
script and authored the following PHP script:
--------------------------------------------------------------------------
$data=join(' ', file($argv[1]));
foreach(explode(' ', $data) as $slowo)
$stat[chop($slowo)]++;
array_multisort($stat, SORT_DESC, array_keys($stat));
foreach($stat as $sl=>$il)
$odata.="$il : $sl\n";
file_put_contents($argv[2], $odata);
--------------------------------------------------------------------------
...which has the same functionality with less actual code lines [7].
I'm a little bit confused, since I considered Python more expressive then
PHP. The more I'm interested in improving my implementation now :)
It looks like this [11 actual code lines]:
--------------------------------------------------------------------------
import sys
corpus = {}
inFile = open( sys.argv[1] )
for word in inFile.read().split():
corpus[word] = corpus.get( word, 0 ) + 1
inFile.close()
words = sorted( ( -freq, word ) for word, freq in corpus.iteritems() )
outFile = open( sys.argv[2], 'w')
for negFreq, word in words:
outFile.write( '%7d : %s\n' % ( -negFreq, word ) )
outFile.close()
--------------------------------------------------------------------------
