我正在接收来自特定国家的顶级艺术家,该艺术家的专辑以及来自lastfm api的专辑的曲目。我没有错误地收到艺术家和专辑,但是在曲目中它出现了:
for album in album_response['album']['tracks']['track']: KeyError: 'album'
问题似乎是因为一些艺术家的名字中有空格,所以我用“+”替换它也用“%2b”替换它,但没有解决方案正常工作它总是出现上面的错误。
chosen = artists[i]['name'].replace(" ", "+")
chosen = '+'.join(artists[i]['name'].lower().split())
chosen = artists[i]['name'].replace(" ", "%2B")
轨道部分出错:
tracks = {}
for i,v in albums.items():
artist = albums[i]['artist'].replace(" ","+")
name = albums[i]['name'].replace(" ", "+")
album_response_data = requests.get('http://ws.audioscrobbler.com/2.0/?method=album.getinfo&format=json&api_key='+api_key+'&artist='+artist+'&album='+name)
album_response = album_response_data.json()
print(album_response)
for album in album_response['album']['tracks']['track']:
title = album['name']
number = album['@attr']['rank']
duration = album['duration']
tracks[ID] = {}
tracks[ID]['title'] = title
tracks[ID]['number'] = number
tracks[ID]['artist'] = albums[i]['artist']
tracks[ID]['album'] = albums[i]['name']
tracks[ID]['albumID'] = albums[i]['ID']
tracks[ID]['duration'] = duration
ID += 1
完整的工作示例:
import requests
api_key = "b088cbedecd40b35dd89e90f55227ac2" #generated for the example
ID= 0
#Get artists from specific country
artists = {}
for i in range(2, 3):
artists_response = requests.get(
'http://ws.audioscrobbler.com/2.0/?method=geo.gettopartists&country=spain&format=json&page=' + str(i) + '&api_key=' + api_key)
artists_data = artists_response.json()
for artist in artists_data["topartists"]["artist"]:
name = artist["name"]
url = artist["url"]
#if ID > 3 continue
artists[ID] = {}
artists[ID]['ID'] = ID
artists[ID]['name'] = name
ID += 1
#Get TopAlbums info from above artists
albums = {}
for i, v in artists.items():
chosen = artists[i]['name'].replace(" ", "+")
topalbums_response = requests.get(
'http://ws.audioscrobbler.com/2.0/?method=artist.gettopalbums&format=json&artist=' + chosen + '&api_key=' + api_key + '&limit=5')
albums_data = topalbums_response.json()
for album in albums_data['topalbums']['album']:

albums[ID]['ID'] = ID
albums[ID]['artist'] = artists[i]['name']
albums[ID]['artistID'] = artists[i]['ID']
albums[ID]['name'] = name
albums[ID]['url'] = url
ID += 1
#Get tracks info of the above albums
tracks = {}
for i,v in albums.items():

答案 0 :(得分:1)
问题不在于某些艺术家在名称中有空格,而是因为您的album_response
字典并不总是有一个名为album
的键。
在for循环中添加print album_response.keys()
,如下所示,
artist = albums[i]['artist'].replace(" ","+")
name = albums[i]['name'].replace(" ", "+")
album_response_data = requests.get('http://ws.audioscrobbler.com/2.0/?method=album.getinfo&format=json&api_key='+api_key+'&artist='+artist+'&album='+name)
album_response = album_response_data.json()
print album_response.keys() # ADDED HERE
for album in album_response['album']['tracks']['track']:
title = album['name']
我得到以下输出:
>>> [u'album']
>>> [u'album']
>>> [u'album']
>>> [u'album']
>>> [u'album']
>>> [u'album']
>>> [u'album']
>>> [u'album']
>>> [u'album']
>>> [u'album']
>>> [u'album']
>>> [u'album']
>>> [u'album']
>>> [u'album']
>>> [u'album']
>>> [u'album']
>>> [u'album']
>>> [u'album']
>>> [u'album']
>>> [u'album']
>>> [u'album']
>>> [u'message', u'links', u'error']
>>> Traceback (most recent call last):
File "test.py", line 58, in <module>
for album in album_response['album']['tracks']['track']:
KeyError: 'album'
请注意,在错误发生之前,album_response.keys()
没有“相册”作为关键字。我不确定你想怎么处理这个,但如果你只是想忽略这种情况,只需添加一个这样的if语句:
tracks = {}
for i,v in albums.items():
artist = albums[i]['artist'].replace(" ","+")
name = albums[i]['name'].replace(" ", "+")
album_response_data = requests.get('http://ws.audioscrobbler.com/2.0/?method=album.getinfo&format=json&api_key='+api_key+'&artist='+artist+'&album='+name)
album_response = album_response_data.json()
if 'album' in album_response.keys():
for album in album_response['album']['tracks']['track']:
title = album['name']
number = album['@attr']['rank']
duration = album['duration']
tracks[ID] = {}
tracks[ID]['trackID'] = ID
tracks[ID]['title'] = title
tracks[ID]['number'] = number
tracks[ID]['artist'] = albums[i]['artist']
tracks[ID]['album'] = albums[i]['name']
tracks[ID]['albumID'] = albums[i]['ID']
tracks[ID]['duration'] = duration
ID += 1
