to read and write json files in python, you can use the built-in `json` module. this module provides functions for encoding python data structures into json strings, as well as decoding json strings into python data structures.
here's a step-by-step tutorial on how to read and write json files in python:
1. *reading json file:*
to read data from a json file, you can use the `json.load()` function. this function reads the json data from a file object and returns a python dictionary.
2. *writing json file:*
to write data to a json file, you can use the `json.dump()` function. this function takes a python dictionary and writes it to a file in json format.
in the code examples above:
we import the `json` module to work with json data.
to read a json file, we use `json.load()` function and provide the file object as an argument.
to write data to a json file, we use `json.dump()` function with the python dictionary and file object as arguments.
the `indent` parameter in `json.dump()` is optional and is used to format the json output for better readability.
make sure to replace `'data.json'` and `'output.json'` with the paths to your actual json files.
by following these steps, you can easily read and write json files in python using the `json` module.
