这是我的第一个问题。
我正在使用YouTube Api v3来接收有关我频道的数据。

我试过这个
results[::-1]
要查看我是否可以修改响应，但它会给我一个错误。我想要做的只是展示我收到的所有信息中的某一部分。

这是我从YouTube获得的回复。现在我只希望它显示'subscriberCount': '12156'
有人知道如何删除除Subscounts以外的所有内容吗？
编辑： 我试过这个

print(myDict['subscriberCount'])
但它给了我这个错误：print（myDict ['subscriberCount']） KeyError：'subscriberCount'
答案 0 :(得分：0)
这样做了！
