Python 错误：字符串索引必须是整数

我正在尝试将json字符串转换为csv文件。 我得到了

错误：字符串索引必须是整数
（所有嵌套键的格式都正确）。
这里的方括号是原因吗

data":[\  

以下是我尝试执行的python文件：

import csv
import json

x="""{

"response":{"status":1,"httpStatus":200,"data":{"page":1,"current":50,"count":11012,"pageCount":221,

"data":[\
{"Offer":{"name":"abc","id":"884"},
"Affiliate":{"company":"POCKET","id":"1494"},
"Goal":{"name":null},
"Stat":{"year":"2015","month":"03","hour":"11","date":"2015-03-13","impressions":"0","gross_clicks":"1","unique_clicks":"1","clicks":"1","conversions":"0"}},

{"Offer":{"name":"qwerty","id":"884"},"Affiliate":{"company":"Rob","id":"1472"},"Goal":{"name":null},"Stat":{"year":"2015","month":"03","hour":"17","date":"2015-03-07","impressions":"0","gross_clicks":"2","unique_clicks":"2","clicks":"2","conversions":"0"}},


{"Offer":{"name":"1000","id":"2586"},"Affiliate":{"company":"Iron","id":"1156"},"Goal":{"name":null},"Stat":{"year":"2015","month":"07","hour":"13","date":"2015-07-07","impressions":"0","gross_clicks":"8628","unique_clicks":"8620","clicks":"8628","conversions":"6"}}],"dbSource":"brdb"},"errors":[],"errorMessage":null}}"""



x = json.loads(x)

f = csv.writer(open("S2.csv", "w",newline=""))
# Write CSV Header, If you dont need that, remove this line
f.writerow(["Offer", "Affiliate", "Goal", "year", "month","hour", "date", "impressions", "gross_clicks", "unique_clicks","clicks","conversions"])
print(x)
for x in x:
    f.writerow([x["response"]["data"]["data"]["Offer"]["name"], 
                x["response"]["data"]["data"]["Affiliate"]["company"], 
                x["response"]["data"]["data"]["Goal"]["name"], 
                x["response"]["data"]["data"]["Stat"]["year"],
                x["response"]["data"]["data"]["Stat"]["month"],
                x["response"]["data"]["data"]["Stat"]["hour"],
                x["response"]["data"]["data"]["Stat"]["date"],
                x["response"]["data"]["data"]["Stat"]["impressions"],
                x["response"]["data"]["data"]["Stat"]["gross_clicks"],
                x["response"]["data"]["data"]["Stat"]["unique_clicks"],
                x["response"]["data"]["data"]["Stat"]["clicks"],
                x["response"]["data"]["data"]["Stat"]["conversions"]
                ])


f.writerow([""])

x[“响应”][“数据”][“数据”]
返回一个列表

因此
x[“response”][“data”][“data”][“Offer”]
在试图访问列表中的键
Offer
时会引发错误。因此，错误
列表索引必须是整数

试试这个：

x["response"]["data"]["data"][0]["Offer"]["name"]

其中
x[“response”][“data”][“data”][0]
将访问列表中的字典，您可以从中访问键
“Offer”
和
“name”
