我正在尝试遍历附加的 JSON 并打印出数据中每个项目的名称和价格。我的问题是它只重复打印名字和价格 50 多次。我错过了什么?什么能让我让它显示下一个项目?这只是我基于代码的示例数据。
我的代码

import requests
request = requests.get('http://example.com/json')
for item in request:
data = request.json()
data = data['items'][0]
price = data['salePrice']
name = data['name']
print name

最佳答案
是因为这一行:
data = data['items'][0]
在这里,您已经在循环的每次迭代中明确访问了第一项。

data = request.json()
items = data['items']
for item in items:
price = item['salePrice']
name = item['name']
print name
