How to add a line to JSON?

Question

Python

How to add data to a line, and not to the end or beginning.
For example:
JSON:

"Users":{

}

You need to add data to users.
And when writing to JSON, a line is written on how to make the JSON file readable.
Thanks in advance)

Answer 1

Read, change key value, write back.

data = json.load(file)
data['Users'] = new_data
json.dump(data, file)

If by "readable" you mean indents, then apply indent to json.dump
json.dump(data, file, indent=4)
