  • Parsing srt subtitles

    - by Vojtech R.
    Hi, I want to parse srt subtitles: 1 00:00:12,815 --> 00:00:14,509 Chlapi, jak to jde s tema pracovníma svetlama?. 2 00:00:14,815 --> 00:00:16,498 Trochu je zesilujeme. 3 00:00:16,934 --> 00:00:17,814 Jo, sleduj. Every item into structure. With this regexs: A: RE_ITEM = re.compile(r'''(?P<index>\d+).(?P<start>\d{2}:\d{2}:\d{2},\d{3}) --> (?P<end>\d{2}:\d{2}:\d{2},\d{3}).(?P<text>.*?)''', re.DOTALL) B: RE_ITEM = re.compile(r'''(?P<index>\d+).(?P<start>\d{2}:\d{2}:\d{2},\d{3}) --> (?P<end>\d{2}:\d{2}:\d{2},\d{3}).(?P<text>.*)''', re.DOTALL) And this code: for i in Subtitles.RE_ITEM.finditer(text): result.append((i.group('index'), i.group('start'), i.group('end'), i.group('text'))) With code B I have only one item in array (because of greedy .*) and with code A I have empty 'text' because of no-greedy .*? How to cure this? Thanks

  • Boto - How to delete a record set from route53 -Tried to delete resource record set but it was not found

    - by Tampa
    I am using the following to delete route53 records. I get no error messages. conn = Route53Connection(aws_access_key_id, aws_secret_access_key) changes = ResourceRecordSets(conn, zone_id) change = changes.add_change("DELETE",sub_domain, "A", 60,weight=weight,identifier=identifier) change.add_value(ip_old) changes.commit() all required fields are present and they match..weight, identifier, ttl=60 etc.\ e.g. test.com. A 111.111.111.111 60 1 id1 test.com. A 111.111.111.222 60 1 id2 I want to delete 111.111.111.222 and the record set. So, what is the proper way to delete a record set? For a record set, I will have multiple values that are distinguished by a unique identifier. When an ip address becomes in active I want to remove from route53.

  • Regex to remove conditional comments

    - by cnu
    I want a regex which can match conditional comments in a HTML source page so I can remove only those. I want to preserve the regular comments. I would also like to avoid using the .*? notation if possible. The text is foo <!--[if IE]> <style type="text/css"> ul.menu ul li{ font-size: 10px; font-weight:normal; padding-top:0px; } </style> <![endif]--> bar and I want to remove everything in <!--[if IE]> and <![endif]--> EDIT: It is because of BeautifulSoup I want to remove these tags. BeautifulSoup fails to parse and gives an incomplete source EDIT2: [if IE] isn't the only condition. There are lots more and I don't have any list of all possible combinations. EDIT3: Vinko Vrsalovic's solution works, but the actual problem why beautifulsoup failed was because of a rogue comment within the conditional comment. Like <!--[if lt IE 7.]> <script defer type="text/javascript" src="pngfix_253168.js"></script><!--png fix for IE--> <![endif]--> Notice the <!--png fix for IE--> comment? Though my problem was solve, I would love to get a regex solution for this.

  • What's going on here? Repeating rows in random list of lists.

    - by Jesse Aldridge
    I expected to get a grid of unique random numbers. Instead each row is the same sequence of numbers. What's going on here? from pprint import pprint from random import random nrows, ncols = 5, 5 grid = [[0] * ncols] * nrows for r in range(nrows): for c in range(ncols): grid[r][c] = int(random() * 100) pprint(grid) Example output: [[64, 82, 90, 69, 36], [64, 82, 90, 69, 36], [64, 82, 90, 69, 36], [64, 82, 90, 69, 36], [64, 82, 90, 69, 36]]

  • Break nested loop in Django views.py with a function

    - by knuckfubuck
    I have a nested loop that I would like to break out of. After searching this site it seems the best practice is to put the nested loop into a function and use return to break out of it. Is it acceptable to have functions inside the views.py file that are not a view? What is the best practice for the location of this function? Here's the example code from inside my views.py @login_required def save_bookmark(request): if request.method == 'POST': form = BookmarkSaveForm(request.POST) if form.is_valid(): bookmark_list = Bookmark.objects.all() for bookmark in bookmark_list: for link in bookmark.link_set.all(): if link.url == form.cleaned_data['url']: # Do something. break else: # Do something else. else: form = BookmarkSaveForm() return render_to_response('save_bookmark_form.html', {'form': form})

  • Timezones and the DateTimeField - Django

    - by RadiantHex
    Hi folks, I'm trying to implement a "time ago" feature, for the displaying of items on a site. As I'm caching the pages I wish to use javascript in order to render the "time ago". Javascript knows local time and problably the Timezone of the local machine so I could play with that, but that would require to hard code the server's timezone. Therefore I'm trying to figure out a simple way to pass a ISO 8601 timestamp, in GMT time. Is there any simple and straight forward way for doing this? Help would be much appreciated! =)

  • How to Pythonically yield all values from a list?

    - by bodacydo
    Suppose I have a list that I wish not to return but to yield values from. What is the most Pythonic way to do that? Here is what I mean. Thanks to some non-lazy computation I have computed the list ['a', 'b', 'c', 'd'], but my code through the project uses lazy computation, so I'd like to yield values from my function instead of returning the whole list. I currently wrote it as following: List = ['a', 'b', 'c', 'd'] for item in List: yield item But this doesn't feel Pythonic to me. Looking forward to some suggestions, thanks. Boda Cydo.

  • Diophantine Equation [closed]

    - by ANIL
    In mathematics, a Diophantine equation (named for Diophantus of Alexandria, a third century Greek mathematician) is a polynomial equation where the variables can only take on integer values. Although you may not realize it, you have seen Diophantine equations before: one of the most famous Diophantine equations is: X^n+Y^n=Z^n We are not certain that McDonald's knows about Diophantine equations (actually we doubt that they do), but they use them! McDonald's sells Chicken McNuggets in packages of 6, 9 or 20 McNuggets. Thus, it is possible, for example, to buy exactly 15 McNuggets (with one package of 6 and a second package of 9), but it is not possible to buy exactly 16 nuggets, since no non- negative integer combination of 6's, 9's and 20's adds up to 16. To determine if it is possible to buy exactly n McNuggets, one has to solve a Diophantine equation: find non-negative integer values of a, b, and c, such that 6a + 9b + 20c = n. Problem 1 Show that it is possible to buy exactly 50, 51, 52, 53, 54, and 55 McNuggets, by finding solutions to the Diophantine equation. You can solve this in your head, using paper and pencil, or writing a program. However you chose to solve this problem, list the combinations of 6, 9 and 20 packs of McNuggets you need to buy in order to get each of the exact amounts. Given that it is possible to buy sets of 50, 51, 52, 53, 54 or 55 McNuggets by combinations of 6, 9 and 20 packs, show that it is possible to buy 56, 57,..., 65 McNuggets. In other words, show how, given solutions for 50-55, one can derive solutions for 56-65. Problem 2 Write an iterative program that finds the largest number of McNuggets that cannot be bought in exact quantity. Your program should print the answer in the following format (where the correct number is provided in place of n): "Largest number of McNuggets that cannot be bought in exact quantity: n" Hints: Hypothesize possible instances of numbers of McNuggets that cannot be purchased exactly, starting with 1 For each possible instance, called n, a. Test if there exists non-negative integers a, b, and c, such that 6a+9b+20c = n. (This can be done by looking at all feasible combinations of a, b, and c) b. If not, n cannot be bought in exact quantity, save n When you have found six consecutive values of n that in fact pass the test of having an exact solution, the last answer that was saved (not the last value of n that had a solution) is the correct answer, since you know by the theorem that any amount larger can also be bought in exact quantity

  • Problems with Snow Leopard, Django & PIL

    - by Cato Johnston
    Hi I am having some trouble getting Django & PIL work properly since upgrading to Snow Leopard. I have installed freetype, libjpeg and then PIL, which tells me: --- TKINTER support ok --- JPEG support ok --- ZLIB (PNG/ZIP) support ok --- FREETYPE2 support ok but when I try to upload a jpeg through the django admin interface I get: Upload a valid image. The file you uploaded was either not an image or a corrupted image. It works fine with PNG files. Any Ideas?

  • Can I treat IronPython as a Pythonic replacement to C#?

    - by Ewan Nathaniel
    Hey guys! I do understand that this topic has been covered in some way at StackOverflow but I'm still not able to figure out the exact answer: can I treat IronPython as a Pythonic replacement to C#? I use CPython every day, I love the Zen :) but my current task is a Windows-only application with a complex GUI and some other features which I would like to implement using .NET.

  • Paramiko and Pseudo-tty Allocation

    - by Jon
    I'm trying to use Paramiko to connect to a remote host and execute a number of text file substitutions. i, o, e = client.exec_command("perl -p -i -e 's/" + initial + "/" + replaced + "/g'" + conf); Some of these commands need to be run as sudo, which results in: sudo: sorry, you must have a tty to run sudo I can force pseudo-tty allocation with the -t switch and ssh. Is it possible to do the same thing using paramiko?

  • pyinstaller: 2 instances of my cherrypy app exe get executed.

    - by d.c
    I have a cherrypy app that I've made an exe with pyinstaller. now when I run the exe it loads itself twice into memory. Watching the taskmanager shows the first instance load into about 1k, then a second later a second instance of hte exe loads into about 3k ram. If I close the bigger one both processes die. If I close hte smaller one only that one dies. Loading the exe with subprocess, if I try to proc.kill(), it only kills the small one leaving the other running in memory. Is this a sideeffect of using cherrypy and pyinstaller together?

  • Simple way to decrease values without making a new attribute?

    - by Jam
    I'm making a program where you're firing a 'blaster', and I have 5 ammo. I'm blasting an alien who has 5 health. At the end I instantiate the player and make him blast 6 times to check that the program works correctly. But the way I've done it makes it so that the amount won't decrease. Is there an easy fix to this, or do I just have to make a new attribute for ammo and health? Here's what I have: class Player(object): """ A player in a shooter game. """ def blast(self, enemy, ammo=5): if ammo>=1: ammo-=1 print "You have blasted the alien." print "You have", ammo, "ammunition left." enemy.die(5) else: print "You are out of ammunition!" class Alien(object): """ An alien in a shooter game. """ def die(self, health=5): if health>=1: health-=1 print "The alien is wounded. He now has", health, "health left." elif health==0: health-=1 print "The alien gasps and says, 'Oh, this is it. This is the big one. \n" \ "Yes, it's getting dark now. Tell my 1.6 million larvae that I loved them... \n" \ "Good-bye, cruel universe.'" else: print "The alien's corpse sits up momentarily and says, 'No need to blast me, I'm dead already!" # main print "\t\tDeath of an Alien\n" hero = Player() invader = Alien() hero.blast(invader) hero.blast(invader) hero.blast(invader) hero.blast(invader) hero.blast(invader) hero.blast(invader) raw_input("\n\nPress the enter key to exit.")

  • Django: A Result Specific Numeration for Pagination.

    - by TheLizardKing
    Simply put I want what http://www.reddit.com/ and http://news.ycombinator.com/ have to the left of every link. A numerated link starting with 1 and continuing to the next page by means of pagination. I really enjoy using generic views and their built-in pagination for Django and it seems to allow me access to these values if I was on page 3 with 2 items per page. {'MEDIA_URL': ''} {'LANGUAGES': '<<languages>>', 'LANGUAGE_BIDI': False, 'LANGUAGE_CODE': 'en-us'} {'debug': True, 'sql_queries': '<<sql_queries>>'} {'messages': [], 'perms': <django.core.context_processors.PermWrapper object at 0xadedeec>, 'user': <User: thelizardking>} {'first_on_page': 5, 'has_next': True, 'has_previous': True, 'hits': 7, 'is_paginated': True, 'last_on_page': 6, 'links_list': [<Link: Funky Town>, <Link: Apple Jax>], 'next': 4, 'page': 3, 'page_obj': <Page 3 of 4>, 'page_range': [1, 2, 3, 4], 'pages': 4, 'paginator': <django.core.paginator.Paginator object at 0xadf914c>, 'previous': 2, 'results_per_page': 2} I know there is an add filter for templates but that's as close as I think I can get and that really doesn't do what I want. Am I going to have to use a custom template filter here or is there something I am not seeing?

  • Scrapy domain_name for spider

    - by Zeynel
    From the Scrapy tutorial: domain_name: identifies the Spider. It must be unique, that is, you can’t set the same domain name for different Spiders. Does this mean that domain_name must be a valid domain name, like domain_name = 'example.com' Or can I name domain_name = 'ex1' The problem is I had a spider that worked with domain name domain_name = 'whitecase.com' Now I created a new spider as an instance of CrawlSpider and named it domain_name = 'wc2' but I am getting the error "could not find spider for domain "wc2""

    I know it's a really simple question, but I have no idea how to google it. how can I do print '<a href="%s">%s</a>' % (my_url) So that my_url is used twice? I assume I have to "name" the %s and then use a dict in the params, but I'm not sure of the proper syntax? just FYI, I'm aware I can just use my_url twice in the params, but that's not the point :)
