怎么使用python提取json文件中的字段 如何用python读取json文件里指定的数据
\u5982\u4f55\u4f7f\u7528python\u63d0\u53d6json\u4e2d\u6307\u5b9a\u5b57\u6bb5\u7684\u6570\u636eimport json
#\u8f7d\u5165\u6570\u636e\uff0c\u5c06json\u53d8\u6210python\u5b57\u5178
data = json.loads(\u4f60\u7684JSON\u6570\u636e)
#\u53d6\u51fa\u5b57\u5178\u91ccKEY_NAME\u8fd9\u4e2akey\u7684\u503c
data.get("KEY_NAME")
import jsonwith open('who.json', 'r') as f: data = json.load(f) dependencies = data['dependencies'] for k, v in dependencies.iteritems(): print(f'{k}@{v}')
例json文件，名字test.json，
{
"verson":"1.4.2" ,
"author":"johanna",
"type":"1"
}python编码:
首先读取json文件内容，利用json.loads()转化为dict类型，遍历每一对key,val
import json
import os
try:
t_str = open('./test.json','r').read()
t_json = json.loads(t_str)
for k,v in t_json.items():
print k,v
except Exception,e:
print str(e)
import json
json.dumps(xx)
import json
使用json模块。
