2. UsingsimplejsonLibrary Another simple option is to use thesimplejsonlibrary, which offers significant performance advantages over thejsonlibrary. You can use itsloads()function to deserialize a string to a Python object. This function also raises theJSONDecodeErrorwhen the JSON string is not val...
importjson if__name__=='__main__': json_str='{"name": "John", "age": 18}' obj=json.loads(json_str) print((obj['name'],obj['age']))# ('John', 18) 下載運行代碼 2.使用simplejson圖書館 另一個簡單的選擇是使用simplejson庫,它提供了顯著的性能優勢超過json圖書館。你可以使用它的...

Encoding basic Python object hierarchies:: >>> import json >>> json.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}]) '["foo", {"bar": ["baz", null, 1.0, 2]}]' >>> print json.dumps("\"foo\bar") "\"foo\bar" >>> print json.dumps(u'\u1234') "\u1234" >>> pri...
JSON in Python is handled using the standard-library json module, which allows for data interchange between JSON and Python data types. JSON is a good data format to use with Python as it’s human-readable and straightforward to serialize and deserialize, which makes it ideal for use in ...

Thejsonlibrary also provides methods for deserializing JSON back into Python objects: json.load(fp): Deserializes JSON data from the file-like objectfpand returns a Python object. json.loads(s): Deserializes the JSON-formatted stringsand returns a Python object. ...
The Pickle dump() and dumps() functions are used to serialize an object. The only difference between them is that dump() writes the data to a file, while dumps() represents it as a byte object. Similarly, load() reads pickled objects from a file, whereas loads() deserializes them ...
In serialization, an object is transformed into a format that can be stored, so as to be able to deserialize it later and recreate the original object from the serialized format.PicklePickling is the process whereby a Python object hierarchy is converted into a byte stream (usually not human ...
