如何解决 IndexError: list index out of range in a list of dict？

Question

对于以下代码，我得到

回溯（最近一次调用）：文件“main.py”，第 24 行，在artist_uri = json_data['artists']['items'][0]['id'] 索引错误：列表索引超出范围。

谁能告诉我如何解决这个问题？

for item in (fd):
  
  artist = item['Name']
  headers = {
    'Accept': 'application/json',
    'Content-Type': 'application/json',
    'Authorization': 'Bearer xxxxx',
    }

  params = (
    ('q', artist),
    ('type', 'artist'),
    )
  response = requests.get('https://api.spotify.com/v1/search', headers=headers, params=params)
  
  json_data = json.loads(response.text) # convert json response to text/dict
  artist_uri = json_data['artists']['items'][0]['id']
  print(artist_uri)

这是因为无法从 Spotify API 中检索到艺术家：“ANAVITÃÂRIA”。 以下是您的脚本在尝试时得到的响应：

{
  "artists" : {
    "href" : "https://api.spotify.com/v1/search?query=ANAVIT%C3%83%C2%83%C3%82%C2%93RIA&type=artist&offset=0&limit=20",
    "items" : [ ],
    "limit" : 20,
    "next" : null,
    "offset" : 0,
    "previous" : null,
    "total" : 0
  }

有时可能是由于名称中的字符。 为了避免这个错误，限速问题并继续循环您可以检查当前API响应中是否有数据以及API响应的状态码检查更新的代码：（请在尝试时更新承载令牌）

import pandas as pd
import requests
import json
import time

fd = pd.read_csv('fd.csv',sep=';',encoding='latin1') # Reading data from csv
fd = fd.T.to_dict().values() # Converting dataframe into list of dictionaries

for item in (fd):
  
  artist = item['Name']
  headers = {
    'Accept': 'application/json',
    'Content-Type': 'application/json',
    'Authorization': 'Bearer xxxxxx',
    }

  params = (
    ('q', artist),
    ('type', 'artist'),
    )
  

  response = requests.get('https://api.spotify.com/v1/search', headers=headers, params=params)
  if response.status_code != 429:
    json_data = json.loads(response.text) # convert json response to text/dict
    
    if (len(json_data['artists']['items']) > 0):
      artist_uri = json_data['artists']['items'][0]['id']
      print(artist_uri)
  else:
    time.sleep(30)
    response = requests.get('https://api.spotify.com/v1/search', headers=headers, params=params)
    json_data = json.loads(response.text) # convert json response to text/dict
    
    if (len(json_data['artists']['items']) > 0):
      artist_uri = json_data['artists']['items'][0]['id']
      print(artist_uri)
