我得到 TypeError：列表索引必須是整數或切片，而不是 str

Question

我正在嘗試抓取此頁面的 json 腳本，但由於某種原因我收到此錯誤

import requests
import json
from bs4 import BeautifulSoup

url = "https://www.amongstfew.com/drops"

r = requests.get(url)

soup = BeautifulSoup(r.content, 'html.parser')

script = soup.find("script", class_="draw_data_json").string.strip()

data = json.loads(script)

print(data['id']['title']['published_scope']['variants'][0])

Answer 1

運行您在json object 上方返回的代碼是一個列表。 所以data[id]試圖用一個不起作用的str索引到一個列表中

這是我的 output 用於data[0]

In [9]: data[0]
Out[9]:

Answer 2

您無法訪問帶有鍵的列表。

下面是導致麻煩的行，以及我認為你想要的代碼：

import requests
import json
from bs4 import BeautifulSoup

url = "https://www.amongstfew.com/drops"

r = requests.get(url)

soup = BeautifulSoup(r.content, 'html.parser')

script = soup.find("script", class_="draw_data_json").string.strip()

data = json.loads(script)

for item in data:
    print(data["id"] data["title"], data["published_scope"], data["variants"][0]])

# print(data['id']['title']['published_scope']['variants'][0]) # this line is causing trouble

每當您操作數據時，將其打印出來，看看如何得到您想要的。
