Python - Structured Data Files

You have a Python list data = [{'id': 1}, {'id': 2}, {'id': 3}]. You want to serialize it to JSON but only include dictionaries where id is greater than 1. Which code correctly does this?

Ajson.dumps([item for item in data if item['id'] > 1])

Bjson.dumps(data.filter(lambda x: x['id'] > 1))

Cjson.dumps(filter(lambda x: x['id'] > 1, data))

Djson.dumps([item for item in data if item.id > 1])

Step-by-Step Solution

Solution:

Step 1: Filter list with list comprehension
Use a list comprehension to select dictionaries where id is greater than 1: [item for item in data if item['id'] > 1].
Step 2: Serialize filtered list to JSON string
Pass the filtered list to json.dumps() to get the JSON string.
Final Answer:
json.dumps([item for item in data if item['id'] > 1]) -> Option A
Quick Check:
Filter with list comprehension, then dumps() [OK]

Quick Trick: Filter with list comprehension before dumps() [OK]

Common Mistakes:

Using filter() without converting to list
Trying to access dict keys with dot notation
Using filter() result directly without list()
