python修改json⽂件内容,⽤python替换json⽂件中的键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 dswith(".json"):
processed_json = "%s%s" % (json_dir_processed, json_file)
json_file = json_dir + json_file
python怎么读取json文件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
此脚本提供以下错误:
File "/opt/rdm/adggeth/ADGG-ETH-02/addfidkey.sh", line 16, in
json_data["grp_farmerdts/hh_id"] = json_data["grp_farmerreg/farmerdetails/farmermobile"]
KeyError: 'grp_farmerreg/farmerdetails/farmermobile'
如何成功替换JSON⽂件的密钥
我的⽰例json⽂件如下：为了便于理解，我删除了json⽂件中的⼤部分细节
{

"grp_farmerreg/hh_country": "1",

}
我的预期产量
