我正在尝试从下面的“count”键中提取整数值，但遇到了字符串索引错误的问题。有人可以提供一种方法吗？

【问题讨论】：

你能提供你正在使用的代码和回溯吗？
json 无效。

标签： python json

【解决方案1】：

data = {'comments':[...]} #Your dict
for item in data['comments']:
    print item['count'] #Whatever operation you want with your number

【讨论】：

OP 没有提到他有字典。问题的标题表明他有一个json
你能发布你正在使用的代码和你得到的错误吗？？
import json import urllib url = raw_input('Enter - ') java = urllib.urlopen(url).read() print java info = json.loads(java) #print info for item in info : 打印项目['cmets'][{'count'}][0]
我得到的错误（想要显示一个 sn-p）是 TypeError: string indices must be integers for line 12
@MCSH，json 不是无效的
