Reading JSON from a file using Python
Deserialization is the opposite of Serialization, i.e. conversion of JSON objects into their respective Python objects. The load() method is used for it. If you have used JSON data from another program or obtained it as a string format of JSON, then it can easily be deserialized with load(), which is usually used to load from a string, otherwise, the root object is in a list or Dict.
Reading JSON from a file using json.load()
The JSON package has json.load() function that loads the JSON content from a JSON file into a dictionary. It takes one parameter:
- File pointer: A file pointer that points to a JSON file.
Python3
import json# Opening JSON filewith open('sample.json', 'r') as openfile: # Reading from json file json_object = json.load(openfile)print(json_object)print(type(json_object)) |

Reading and Writing JSON to a File in Python
The full form of JSON is Javascript Object Notation. It means that a script (executable) file which is made of text in a programming language, is used to store and transfer the data. Python supports JSON through a built-in package called JSON. To use this feature, we import the JSON package in Python script. The text in JSON is done through quoted-string which contains the value in key-value mapping within { }. It is similar to the dictionary in Python.
