json相关

序列化与反序列化

# 读取文件
f = open("input_compensate.txt", encoding='utf-8')
input_str = f.read()
f.close()
# 文件内容json转字典
input_dict = json.loads(input_str)
# 字典转json，ensure_ascii默认为true
json.dumps(expense_feature, ensure_ascii=False)

json格式化输出

json库方法

# import json
# print json.dumps({'a': 'Runoob', 'b': 7}, sort_keys=True, indent=4, separators=(',', ': '))
{
    "a": "Runoob",
    "b": 7
}

命令行格式化

# echo '{"name":"weick","age":"22","sex":"male"}' | python -m json.tool

{
    "age": "22",
    "name": "weick",
    "sex": "male"
}

# python -m json.tool demo.json
