Py 格式化输出

想倒腾一下，输入json，显示字符串，
输入py 数据格式字符串，输出显示json
1，依赖库：json
     
2，代码：

import json


jStr = ['foo', {'bar': ('baz', None, 1.0, 2),'success' : 'true'} , {'boob': ('acb', True, 5.0, 2),'success' : 'false'}]
jsonDump = json.dumps(jStr, indent=4)
print 'jsonDump:', jsonDump

jsonS = [
 {
  "NincM": {
   "year": {
    "string": "2015",
    "value": "2015"
   },
   "month": {
    "string": "November",
    "value": "11"
   }
  },
  "reservedMonthList": [
   "20",
   "21",
   "22",
   "23"
  ]
 },
 {
  "yearMonth": {
   "year": {
    "string": "2012",
    "value": "2012"
   },
   "month": {
    "string": "December",
    "value": "12"
   }
  },
  "reservedMonthList": [
   "7",
   "8",
   "9",
   "10",
   "11",
   "12",
   "13"
  ]
 }
]

jsonNoD = json.dumps(jsonS)
print 'jsonNoD:', jsonNoD

输出：

jsonDump: [
    "foo",
    {
        "bar": [
            "baz",
            null,
            1.0,
            2
        ],
        "success": "true"
    },
    {
        "boob": [
            "acb",
            true,
            5.0,
            2
        ],
        "success": "false"
    }
]

<type 'str'> '{"price": 542.23, "name": "ACME", "shares": 100}'
<type 'dict'> {u'price': 542.23, u'name': u'ACME', u'shares': 100}
%r %r %r %r
1 2 3 4
one two three four
1 2 3 4
'one' 'two' 'three' 'four'

pprint

jStr = ['foo', {'bar': ('baz', None, 1.0, 2),'success' : 'true'} , {'boob': ('acb', True, 5.0, 2),'success' : 'false'}]

对比输出：
from pprint import pprint
pprint(jStr)
print type(json.loads(json_str)), json.loads(json_str)
输出：


 ['foo',
 {'bar': ('baz', None, 1.0, 2), 'success': 'true'},
 {'boob': ('acb', True, 5.0, 2), 'success': 'false'}]

<type 'dict'> {u'price': 542.23, u'name': u'ACME', u'shares': 100}

3，万能匹配符　％ｒ
直接上例

formatr = '%r %r %r %r'
print formatr
print '%d %d %d %d'%(1,2,3,4)
print '%s %s %s %s'%('one', 'two', 'three', 'four')
print formatr % (1, 2, 3, 4)
print formatr % ('one', 'two', 'three', 'four')
