用python替换JSON文件中的密钥

我正在做一个简单的python脚本来替换JSON文件中的一个键，下面是我的python脚本

import json
import os

json_dir="/opt/rdm/adggeth/ADGG-ETH-02/20181008/"
json_dir_processed="/opt/rdm/adggeth/ADGG-ETH-02/20181008updated/"
for json_file in os.listdir(json_dir):
    if json_file.endswith(".json"):
        processed_json = "%s%s" % (json_dir_processed, json_file)
        json_file = json_dir + json_file
        print "Processing %s -> %s" % (json_file, processed_json)
        with open(json_file, 'r') as f:
            json_data = json.load(f)
            if "grp_farmerreg/farmerdetails/farmermobile" not in json_data:
                json_data["grp_farmerreg/farmerdetails/farmermobile"] = json_data["grp_farmerdts/hh_id"]
        with open(processed_json, 'w') as f:
            f.write(json.dumps(json_data, indent=4))
    else:
        print "%s not a JSON file" % json_file

此脚本显示以下错误：

    File "/opt/rdm/adggeth/ADGG-ETH-02/addfidkey.sh", line 16, in <module>
    json_data["grp_farmerdts/hh_id"] = json_data["grp_farmerreg/farmerdetails/farmermobile"]
KeyError: 'grp_farmerreg/farmerdetails/farmermobile'

我的预期产出

{

    "grp_farmerreg/members_no": "1", 
    "grp_farmerreg/hh_country": "1", 
    "_bamboo_dataset_id": "", 
    "_tags": [], 
    "grp_farmerreg/totanim": "6", 
    "gpsloc": "7.0854258 38.6111001 1674.300048828125 17.0", 
    "grp_farmerreg/farmerdetails/farmermobile": "0913886615", 
    "grp_farmerdts/hh_id":"0913886615", 
    "grp_farmerreg/grpdetails2/nmale6to14": "1", 
    "grp_farmerreg/farmerdetails/farmerhhhead": "1", 
    "grp_farmerreg/grpdetails2/nfem15to64": "0", 
    "meta/instanceID": "uuid:008aea99-810e-4dbc-9235-4d02b8e8d36b", 
    "_duration": "",     
    "grp_farmerreg/grpdetails2/nfem6to14": "1", 
    "grp_farmerreg/grp_e1_ctlca/cattletotalowned": "6", 
    "start_time": "2018-12-24T11:24:53.034+03", 
    "_uuid": "008aea99-810e-4dbc-9235-4d02b8e8d36b", 

}

试着换一下台词

如果grp_farmerreg/farmerdetails/farmermobile不在json_数据中： json_数据[grp_farmerreg/farmerdetails/farmermobile]=json_数据[grp_farmerdts/hh_id] 与

如果json_数据中的grp_farmerreg/farmerdetails/farmermobile： json_数据[grp_farmerdts/hh_id]=json_数据[grp_farmerreg/farmerdetails/farmermobile] del json_数据[grp_farmerreg/farmerdetails/farmermobile]

我尝试过你的解决方案，但我得到了相同的错误@Julian MindeDid你是否也更改了我答案的第一行？Key错误表示json_数据中不存在Key grp_farmerdts/hh_id，这似乎是正确的。但是，通过分配它，您可以添加它，这应该很好。如果您尝试此解决方案，但出现密钥错误，则应提及另一个密钥。
