Last.FM API Help!

[zaz102]

Hello,

I am looking to create and share a MusicBrainz Picard plugin that pulls information that automatically rates your music library using info from Last.FM API. However, I am not a very experienced programmer and am not sure how to get the data I need.

I am looking to get the listeners and playcount values from Last.FM GetInfo webservice:

http://ws.audioscrobbler.com/2.0/?method...6e8e33f2ee

I was able to get this data using xml.etree.ElementTree and pylast libraries in python, but I do not know how to get these to work with MusicBrainz Picard.

I wanted to see if anybody had any other ideas to get those values.

Thank you!

I wanted to see if anybody had any other ideas to get those values.

A common way is to use Requests and BS.

from bs4 import BeautifulSoup import requests   url = 'http://ws.audioscrobbler.com/2.0/?method=artist.getinfo&artist=Cher&api_key=0a8b8f968b285654f9b4f16e8e33f2ee' url_get = requests.get(url) soup = BeautifulSoup(url_get.content, 'html.parser') listeners = soup.find('listeners').text play_count = soup.find('playcount').text print(listeners) print(play_count)

Output:
1058399
14397145

Thanks. This is where I am ignorant though.

I extracted the BS4 library and copied it into my plugin's folder. I was expecting for it to pick it up, but it does not. Instead, I get an error message "ImportError: No module named bs4".

Note that I do not want to install the library the traditional way since it will be used as a plugin. From my experience, MusicBrainz Picard does not pick it up that way.

Any ideas how to have it be picked up by the application.

In order to import the bs4 library, I tried adding the code:

import sys
sys.path.append('./bs4')
import bs4

I am receiving the same error message.

My path is:

testplugin\
testplugin.py
bs4

Any ideas?

Any ideas?

Can do it in a more dirty way using no 3-party modules,can make it easier if using this in a plugin.

import urllib.request import re   url = urllib.request.urlopen('http://ws.audioscrobbler.com/2.0/?method=artist.getinfo&artist=Cher&api_key=0a8b8f968b285654f9b4f16e8e33f2ee') site = url.read().decode('utf-8') listeners = re.search('<listeners>(\d+)', site).group(1) play_count = re.search('<playcount>(\d+)', site).group(1) print(listeners, play_count)

Output:
1058705 14402632

Thank you for your help.

Interestingly enough, the plugin still couldn't find it, but I was able to get it work by copying the library into the plugin folder.

Also, I had to remove the request part from urllib. See below:

import urllib

url = urllib.urlopen('http://ws.audioscrobbler.com/2.0/?method=artist.getinfo&artist=Cher&api_key=0a8b8f968b285654f9b4f16e8e33f2ee')

Not sure why I had to make the changes above, but it's working so I am very happy. Thanks again!

Because you(or library) use Python 2,i always write code for Python 3 if not specify that code has to be for Python 2.
If it's this library you use MusicBrainz Picard,so do it use Python 3,also a 3 :: Only tag.
Here form setup.py:

1 2 3 4 5 6 7 8 9 10 11 12 13 14

'classifiers': [         'License :: OSI Approved :: GNU General Public License v2 or later (GPLv2+)',         'Development Status :: 5 - Production/Stable',         'Programming Language :: Python :: 3',         'Programming Language :: Python :: 3 :: Only',         'Programming Language :: Python :: 3.5',         'Programming Language :: Python :: 3.6',         'Operating System :: Microsoft :: Windows',         'Operating System :: MacOS',         'Operating System :: POSIX :: Linux',         'Topic :: Multimedia :: Sound/Audio',         'Topic :: Multimedia :: Sound/Audio :: Analysis'     ] }

If it woks then all is okay

You have already helped me so much, but I have one more question.

For the URL request, I actually have artist (Cher) as a variable. It seems when the request is made to the website, it's doesn't properly encode the variable. This becomes apparent when there is a special character (e.g. Sonny & Cher). I believe it is coming up as "&" rather than percent-encoding it to "%26". I tried messing around with urlencode, urlquote, and replace, but I am obviously not doing it correctly. Any ideas on how to solve this issue?

>>> from urllib.parse import urlencode >>> >>> artist = 'Sonny & Cher' >>> s = urlencode({'artist': artist}) >>> s 'artist=Sonny+%26+Cher'   >>> # Only last part >>> s.split('=')[1] 'Sonny+%26+Cher'
