Python - Structured Data Files

You have a nested dictionary:

data = {'person': {'name': 'Eve', 'age': 28}, 'city': 'Paris'}

Which code correctly formats this data as pretty JSON with 4 spaces indentation and sorted keys at all levels?

Ajson.dumps(data, indent=4, sort_keys=True)

Bjson.dumps(data, indent=4, sort_keys=False)

Cjson.dumps(data, indent='4', sort_keys=True)

Djson.dumps(data, indent=2, sort_keys=True)

Step-by-Step Solution

Solution:

Step 1: Choose correct indent and sort_keys values
To get pretty JSON with 4 spaces indentation, use indent=4 as integer. To sort keys at all levels, use sort_keys=True.
Step 2: Exclude incorrect options
json.dumps(data, indent=4, sort_keys=False) disables sorting keys. json.dumps(data, indent='4', sort_keys=True) uses string '4' for indent, which is invalid. json.dumps(data, indent=2, sort_keys=True) uses 2 spaces indent, not 4.
Final Answer:
json.dumps(data, indent=4, sort_keys=True) -> Option A
