我正在尝试从REST API生成的json中读取一些键。我们的服务器上没有安装熊猫，所以我不能使用json_normalize并且python版本是2.6.6。
我将从文件中读取数据。因此，首先设置将使用json.load加载：
import json
with open('response.json','r') as f:
data = json.load(f)
现在，我正在尝试循环每个响应并从中选择值。
示例响应：

对于每个响应，我必须从[claimLineDetail]中选择ClaimId，claimeLineNo，protocolPrice，capitatedInd
我需要获取这些值并将其放入csv文件中以进行进一步处理。 如果我遍历值：
for element in data :
for key in element['claimsHeader']['claimLineDetail']:
print key['claimLineNo'],key['agreementPrice'],key['capitatedInd']['code']
output :
1 125.0000 N
2 125.0000 N
我应该如何在每一行中添加ClaimId？以及将以上输出转换为字典格式的最佳方法是什么，以便我可以使用DictWriter使用以下代码将这些记录写入csv。
with open(outfile, 'w') as f:
for element in data:
flat_data = #output of above#
csvwriter = DictWriter(f,flat_data[0].keys(),lineterminator='\n')
csvwriter.writerows(flat_data)
答案 0 :(得分：0)
只需将element['claimsHeader']['claimId']添加到print。如果您只想逐行将循环的输出写入文件，请使用文件操作将其包装：
with open(outfile, 'wb') as f:
for element in data:
for key in element['claimsHeader']['claimLineDetail']:
outputline = element['claimsHeader']['claimId']+" "+str(key['claimLineNo'])+" "+key['agreementPrice']+" "+key['capitatedInd']['code']+"\n"
f.write(outputline.encode('latin-1'))
print outputline
