i use regex quite bit find , replace, , want use best practices as possible. i understand difference between + , * characters. reference * find matches specified phrase, , + find last instance of specified phrase. that being said, when regex phrases on internet, see lot of people using + feel using * . standard use + instead of * on generic regex phrases or there convention missing? the site you've linked great, you're misunderstanding definitions of * , + . essentially, * means "zero or more," + means "one or more." in other words: x* means "any number of x characters in row, or possibly none @ all. " x+ means "any number of x characters in row, at least one. " so x+ equivalent xx* (or x*x ). both have infinite upper limit, different lower limits. as far 1 standard/best practice, answer "neither," since both have different meanings. however, if you're trying match 1 or more of so

my program keeps randomly skipping out letters! example, 'coolstory' becomes 'yrotsloc' , 'awesome' becomes 'mosewa' here code: def reverse(text): length = len(text) reversed_text = [] in range(0,length + 1): reversed_text += [''] original_list = [] l in text: original_list.append(l) new_place = length - (original_list.index(l)) reversed_text[new_place] = l return "".join(reversed_text) this happens when have duplicate letters because original_list.index(l) will return same value same l . new_place same 2 of same letters @ different locations. one common way reverse strings in python slicing: >>> s = "hello" >>> s[::-1] 'olleh' you can use reversed() , returns reversed object (not string). better option if want iterate on string in reverse order: >>> c in reversed(s): ... print c ... o l l e h

there page list of urls, when user clicks on 1 of url, jquery modal popup opens list of elements. items in list added dynamically doing ajax call. each item in list has raty & timeago (both jquery plugins){"5 star rating, 2 months ago"}. now problem - typically execute javascript functions related these plugins @ time of page load in document.ready event. however, these functions need executed after items added & ready processing. what name of event handle? edit:- easier way visualize : when add comments question on stackoverlow; can see "added 5 minutes ago". part of counting time & showing 'time ago' handled 'time ago' plugin. function (timeago) must executed on on addition of element(comment in case of stackoverflow). want know handle execute function on addition of new element dom tree. you can use event delegation using jquery on dynamically added elements. $(document).on('click', '.classname
