python json 长整型 python处理json字符串

从文件中解析json类型数据

import  json

a = [json.loads(line) for line in open('E:/python/data/c.json')]

需要将c.json 文件另存为,无 BOM UTF-8

import json

import os
def pro_json(line):
element=[]
codejson=json.loads(line)
cust_pty_no=codejson['cust_pty_no']
entrust_no=codejson['entrust_no']
tradingcode=codejson['tradingcode']
if 'error' in codejson:
return
else:
element.append(cust_pty_no)
element.append(entrust_no)
element.append(tradingcode)
return element
def read_json(fname):
data=[]
f=open(fname,'r')
for line in f:
temp=pro_json(line)
if temp!=None:
 data.append(temp)
return data


fname='E:\\test\\fruit.txt'
data=read_json(fname)
print data



fruit.txt

{"cust_pty_no":10,"entrust_no":"1001","tradingcode":"A1001","error":{"reason":"faile","times":10,"repairable":"NO"}}
{"cust_pty_no":11,"entrust_no":"1002","tradingcode":"A1002"}
{"cust_pty_no":13,"entrust_no":"1002","tradingcode":"A1005"}
