In Python, you can use the json library to parse a JSON string and retrieve its attribute values.<\/p>\n

Assume we have the following JSON string:<\/p>\n

import<\/span> json\r\n\r\njson_str = '{\"name\": \"John\", \"age\": 30, \"city\": \"New York\"}'<\/span>\r\n<\/code><\/pre>\n
To obtain the values of the attributes, you can follow these steps:<\/p>\n
    \n
  1. parse a JSON string into a Python object.<\/li>\n<\/ol>\n
    data = json.loads(json_str)\r\n<\/code><\/pre>\n
      \n
    1. obtain<\/li>\n<\/ol>\n
      name = data[\"name\"<\/span>]\r\nage = data.get(\"age\"<\/span>)\r\ncity = data.get(\"city\"<\/span>)\r\n<\/code><\/pre>\n
      Here is the complete code:<\/p>\n
      import<\/span> json\r\n\r\njson_str = '{\"name\": \"John\", \"age\": 30, \"city\": \"New York\"}'<\/span>\r\ndata = json.loads(json_str)\r\n\r\nname = data[\"name\"<\/span>]\r\nage = data.get(\"age\"<\/span>)\r\ncity = data.get(\"city\"<\/span>)\r\n\r\nprint<\/span>(name)  # \u8f93\u51fa: John<\/span>\r\nprint<\/span>(age)  # \u8f93\u51fa: 30<\/span>\r\nprint<\/span>(city)  # \u8f93\u51fa: New York<\/span>\r\n<\/code><\/pre>\n
      Note: If a property does not exist in a JSON string, accessing it using data[“property”] will raise a KeyError exception, while using the get() method will return either None or a specified default value.<\/p>\n","protected":false},"excerpt":{"rendered":"
