python - String to float and regex -

-

i have problem regex , string...

i need solution in regex code take float number of string. don't know why code doesn't work.

from bs4 import beautifulsoup import urllib2 re import sub    url = 'http://www.ebay.es/itm/pet-shop-boys-official-promo-barcelona-electric-tour-beer-cerveza-20cl-bottle-/111116266655' #raw_input('dime la url que deseas: ') code = urllib2.urlopen(url).read(); soup = beautifulsoup(code) info = soup.find('span', id='v4-27').contents[0] print info   info = sub("[\d]+,+[\d]", "", info) = float(info) print

\d means non-digits. need use \d instead. here details: http://en.wikipedia.org/wiki/regular_expression#character_classes

updated

i see, approach replace non-digits chars. mind, match needed information more clear:

>>> import re >>> s = "15,00 eur" >>> price_string = re.search('(\d+,\d+)', s).group(1) >>> price_string '15,00' >>> float(price_string.replace(',', '.')) 15.0

this question has answer here: why write “.call(this)” @ end of javascript anonymous function? [duplicate] 4 answers what kind of design pattern , significance of using closure? (function(){ // code here }).call(this); edit then difference between above code , following this keyword still refer same object in both ways. (function(){ // code here })(); thats invoked function expression. more info here: http://benalman.com/news/2010/11/immediately-invoked-function-expression/ the purpose run code while protecting scope (so variables declared within don't leak out global scope. update call sets value of this function being applied on. without it, value set window object, there set outer scope.
