Fastest way to find first match index of lots of strings in large text
I have implemented a quick find algorithm in python 2.7.13. It does what I want but I have small performance issues. These are my algorithms specificities : I have a text that is an HTML article, it is generally between 5 000 to 50 000 characters but it can be as big as 300 000 characters. I have a list of "words" that can contain special characters (é,à,ø,/...) and spaces, generally hundreds to a few thousands words. Words are 2 to 256 characters long. I need to ignore found items contained in HTML tags I need indexes in text of matches I only need the first match for each words What I have is this implementation : def find_indexes(text, words): words_indexes = [] found_words = [] authorized_characters = [u' ', u'.', u':', u';', u'?', u'!', u'¿', u'¡', u'…', u'(', u')'] text_length = len(text) for j, word in enumerate(words): i = 0 # This loop serves to go to the next word find if the first one isn't valid (contained in another word or in HTML tag) while i != -1: i = text.find(word, i + 1) if i + 1 + len(word) < text_length: # We check the before and … -

Django complex filter and order
I have 4 model like this class Site(models.Model): name = models.CharField(max_length=200) def get_lowest_price(self, mm_date): '''This method returns lowest product price on a site at a particular date''' class Category(models.Model): name = models.CharField(max_length=200) site = models.ForeignKey(Site) class Product(models.Model): name = models.CharField(max_length=200) category = models.ForeignKey(Category) class Price(models.Model): date = models.DateField() price = models.IntegerField() product = models.ForeignKey(Product) Here every have many category, every category have many product. Now product price can change every day so price model will hold the product price and date. My problem is I want list of site filter by price range. This price range will depends on the get_lowest_price method and can be sort Min to Max and Max to Min. Already I've used lambda expression to do that but I think it's not appropriate sorted(Site.objects.all(), key=lambda x: x.get_lowest_price(the_date)) Also I can get all site within a price range by running a loop but this is also not a good idea. Please help my someone to do the query in right manner. -

Copy and past image from Google to my app
I am a totaly new on javascript so I ask your help about this. In my app, I have a textarea to insert a text. Any scripts are not interpreted of course. But there is an exception for the URL links which are preserved. What I would like to do is, if I post the URL of an image like http://image.jpg or png in my textarea, so the image will be displayed. So I think the issue is to know how transforming automatically this : <a href="image.jpg">image.jpg</a> to this : <img src="image.jpg"> I have in backend a TinyMCE Editor to write some articles. So it works fine with it. I can copy and past images links and images are displayed instead of their URL. But in a basic textarea it doesn't work. I have a BONUS QUESTION ! :) In Google image or whatever website, on any images, I can right click on it and choose to copy the image. But I can't paste it where I want. In my TinyMCE Editor, it's working fine. But It paste nothing on a textarea. I should at least have the URL link, doesn't it ? Thank you -
