TypeError:列表索引必须是整数或片，而不是python循环中的str

Question

我一直在寻找其他的答案，比如说（this），但运气不好。我正在编写一个脚本来从API中提取数据。你知道吗

我想循环遍历结果字典并提取每个结果的细节，例如名称、总体等json.dumps文件这是：

对Python还不熟悉，所以如果有更好的方法，我愿意接受建议！你知道吗

在我的测试代码中，我有：

print(jsonResponse["results"][1]["name"])

我可以手动将1改为其他数字，并得到正确的名称打印出来。你知道吗

如果我使用这个，我会得到“list index must be integers or slices，not str”消息

for i in jsonResponse:
            print(jsonResponse["results"][i]["name"])

Answer 1

1. 您希望循环jsonResponse["results"]中的元素，而不是jsonResponse。你知道吗
2. 循环将提供实际的元素，而不是它们的索引。你知道吗

这样你就可以：

for item in jsonResponse["results"]:
    print(item["name"])
