Get artist name

Question

I'm trying to get the names of my top 3 artists of last week with pylast (https://github.com/pylast/pylast) but I run into an error or get I get None as a result and I don't see what I'm doing wrong. pylast is a Python interface to Last.fm.

My code:

import pylast

API_KEY = ""
API_SECRET = ""

username = ""
password_hash = pylast.md5("")

network = pylast.LastFMNetwork(api_key=API_KEY, api_secret=API_SECRET, username=username, password_hash=password_hash)

user = network.get_authenticated_user();

weekly_artists = user.get_weekly_artist_charts();

# Keep the first three artists.
del weekly_artists[3:]

# Print the artist name and number of songs(weight).
for weekly_artist in weekly_artists:
  artist,weight = weekly_artist

  print (artist.get_name())
  print (artist.get_correction())

artist.get_name() returns

None

artist.get_correction() returns

Traceback (most recent call last):
  File "G:\projects\python\lastfm_weekly\lastfm-weekly.py", line 28, in <module>
    print (artist.get_correction())
  File "C:\Users\..\Python\Python36-32\lib\site-packages\pylast\__init__.py", line 1585, in get_correction
    self._request(self.ws_prefix + ".getCorrection"), "name")
  File "C:\Users\..\Python\Python36-32\lib\site-packages\pylast\__init__.py", line 1029, in _request
    return _Request(self.network, method_name, params).execute(cacheable)
  File "C:\Users\..\Python\Python36-32\lib\site-packages\pylast\__init__.py", line 744, in __init__
    network._get_ws_auth()
AttributeError: 'str' object has no attribute '_get_ws_auth'

What am I doing wrong?

Answer 1

Here is a quick and dirty solution, i'm sure someone will provide something better but i just installed the package to test and it works.

network = pylast.LastFMNetwork(api_key=API_KEY, api_secret=API_SECRET)

artists = network.get_top_artists()
del artists[:3]

for i in artists:
    artist, weight = i

    print('Artist = {}. Weight = {}'.format(artist, weight))

I'm not really familiar with the package, I just installed it to help out with this but I do wonder what "get_name()" and "get_correction()" are as they're not in your provided code.

If they're not functions you created / are defined within your code then I'd look there for the problem.

Also, you're authenticating the user but the documentation explicitly states you don't need to unless you're writing data.
