原文json.dumps loads 终于区分出来了

原来每次遇到json loads/dumps始终搞不清方向,写段代码试下:

[python] view plain copy print?
import json dict_ = {1:2, 3:4, "":""} # test json.dumps print type(dict_), dict_
json_str = json.dumps(dict_)
print "json.dumps(dict) return:"
print type(json_str), json_str # test json.loads
print "\njson.loads(str) return"
dict_2 = json.loads(json_str)
print type(dict_2), dict_2

程序结果:

<type 'dict'> {'': '', 1: 2, 3: 4}
json.dump(dict) return:
<type 'str'> {"": "", "": 2, "": 4} json.loads(str) return
<type 'dict'> {u'': u'', u'': 2, u'': 4}

总结:

json.dumps : dict转成str

json.loads:    str转成dict

如此简单。
