期望用双引号括起来的属性名称 - 使用Python将字符串转换为json对象

Question

I am trying to convert a string to JSON using python using the following code:

myStr = '[{u"total": "54", u"value": "54", u"label": u"16 Sep"}, {u"total": "58", u"value": "4", u"label": u"16 Sep"}, {u"total": "65", u"value": "7", u"label": u"16 Sep"}, {u"total": "65", u"value": "0", u"label": u"16 Sep"}]'

import json
json.loads(myStr)

I get the following error:

ValueError: Expecting property name enclosed in double quotes: line 1 column 3 (char 2)

This makes no sense as every property has double quotes, not single ones. Any help?

Answer 1

Remove the unicode qualifier from the string. json.loads assumes the property names are already in unicode.

Answer 2

import json
myStr = '[{"total": 54, "value": 54, "label": "u16 Sep"}, {"total": 58, "value": 4, "label": "u16 Sep"}, {"total": 65, "value": 7, "label":" u16 Sep"}, {"total": 65, "value": 0,"label": "u16 Sep"}]'
obj = json.loads(myStr)
print(repr(obj))

You try load incorrect JSON, you can check it here . I edit your json and it work.

Here You find JSON Syntax rules

Answer 3

Putting together the puzzle pieces from this question and Getting SyntaxError: JSON Parse error: Expected '}' when trying to convert a string into JSON using javascript , you want to do:

myStr = [{u"total": "54", u"value": "54", u"label": u"16 Sep"}, {u"total": "58", u"value": "4", u"label": u"16 Sep"}, {u"total": "65", u"value": "7", u"label": u"16 Sep"}, {u"total": "65", u"value": "0", u"label": u"16 Sep"}]

import json
print(json.dumps(myStr))

Then copy paste the outputted string into javascript.
