Python 键盘错误熊猫

我正在尝试使用Pandas的

JSON\u normalize

方法读取嵌套的JSON。我试图使用其中一个字段作为

记录路径

。我还包括了

errors='ignore'

，以忽略由于缺少键而导致的任何错误。你能帮我一下我做错了什么吗

这里是JSON-

这是密码-

db = mongo_client.conciselogs
col = db.logs
cursor = col.find({"message.extract.request.USER_EVENT_LOGGING.payload.eventType":"audibleSummaryUsage"})
mongo_docs = list(cursor)
df = pd.json_normalize(mongo_docs, ['message.extract.request.USER_EVENT_LOGGING.payload.data'], errors = 'ignore')
df.to_csv('sample_data0220_3.csv', index=False)```

您的

记录路径

参数不正确，它应该是一个列表：

df=pd.json\u规范化(
mongo_博士，
['message'，'extract'，'request'，'USER_EVENT_LOGGING'，'payload'，'data']，#list，而不是'key.key.key'
错误=“忽略”，
)
df.to_csv（'sample_data0220_3.csv'，index=False）

输出：

name,value
userAction,DISMISSED
employeeTenure,3.9
ffc,1234
ntid,abcd
isAccountView,true
userAction,DISMISSED
title,abcd
jobType,
jobClassCd,
userAction,DISMISSED
userAction,DISMISSED
employeeTenure,3.9
jobType,
jobClassCd,
ntid,dfer
ffc,3456
title,erty
isAccountView,true
