Resource for learning

Hello,

Can you suggest good resources for learning Python and Kodi addons development?
Thanks

Hello,

If you want to learn Python, I suggest:
- Youtube tutorials (I am learning python with videos in my mother language) to get concepts.
- A good IDE with inspection code can help to improve and avoid common errors, I use pyCharm.
- The Hitchhiker’s Guide to Python! http://docs.python-guide.org/en/latest/, tips and advices to code python """in the correct way"""(pythonic).
- Python main site https://www.python.org/

Kodi, you should check official wiki or forum and dive in internet, the problem with Kodi that I had many times,it's the documentation is missing or outdated.

Good luck, and enjoy python

P.D: Kodi uses python 2.x, so considerate it for your development.

Hola.

is this can help me?

Yes, quite.

You can assert to give you the courage to create a script to test the connector nowvideo.py with the format "nowvideo.to/video/<id>" (not premium links, only free).
Something like this:

Código: Seleccionar todo

# -*- coding: utf-8 -*-
#------------------------------------------------------------
# pelisalacarta - XBMC Plugin
# Conector para nowvideo
# http://blog.tvalacarta.info/plugin-xbmc/pelisalacarta/
#------------------------------------------------------------

import re

from core import scrapertools
from core import logger

def get_video_url(page_url, premium=False, user="", password="", video_password="" ):
    logger.info("[nowvideo.py] get_video_url(page_url='%s')" % page_url)

    data = scrapertools.cache_page( page_url )

    stepkey = scrapertools.get_match(data,'name="stepkey" value="([^"]+)"')
    data = scrapertools.cache_page( page_url, post='stepkey='+stepkey+'&submit=submit' )

    flashvar_filekey = scrapertools.get_match(data,'flashvars.filekey=([^;]+);')
    filekey = scrapertools.get_match(data,'var '+flashvar_filekey+'="([^"]+)"')

    ## API
    video_id = scrapertools.get_match(page_url,"/([a-z0-9]+)$")
    url = 'http://www.nowvideo.to/api/player.api.php?key=%s&file=%s' % (filekey, video_id)

    data = scrapertools.cache_page(url)

    if "The file is being converted" in data:
        return [[" - [B][COLOR red]SIN VÍDEO[/COLOR][/B] - [COLOR pink]El fichero está en proceso[/COLOR]", ""]]
    if "The video is being transfered" in data:
        return [[" - [B][COLOR red]SIN VÍDEO[/COLOR][/B] - [COLOR pink]El vídeo está siendo transferido[/COLOR]", ""]]
    if "no longer exists" in data:
        return [[" - [B][COLOR red]SIN VÍDEO[/COLOR][/B] - [COLOR pink]El fichero ha sido borrado[/COLOR]", ""]]

    media_url = re.sub(r"^url=", "", data.replace("flv&","flv?"))

    return [[scrapertools.get_filename_from_url(media_url)[-4:] + " [nowvideo]", media_url]]

def find_videos(data):
    encontrados = set()
    devuelve = []

    patronvideos  = 'nowvideo.../video/([a-z0-9]+)'
    logger.info("[nowvideo.py] find_videos #" + patronvideos + "#")
    matches = re.compile(patronvideos,re.DOTALL).findall(data)

    for match in matches:
        titulo = "[nowvideo]"
        url = "http://www.nowvideo.to/video/" + match
        if url not in encontrados:
            logger.info("  url=" + url)
            devuelve.append( [ titulo , url , 'nowvideo' ] )
            encontrados.add(url)
        else:
            logger.info("  url duplicada=" + url)

    return devuelve

The py files, in addon SoD, are also a good manual or guide to follow.

Thanks Robalo!

You're welcome

If you testeas with false urls, the script forces you to use some method of debugging.

Personally I prefer not to turn on verbose log, too much information. Instead insert lines to detect the cause that stops the script ('print "....."' or 'import xbmc + xbmc.log (".....")' if I'm with kodi-jarvis)

It is important to know where the script stops and why.

Now you have two tasks, learn python and methods of debugging for kodi + addon.

I just found this tutorial and it's really good for newbies
