Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) v1.2AutomationEasy
A network engineer is using a Python script to interact with a network device. The device's API returns data in JSON format. The engineer needs to parse this JSON data into Python objects so that the script can easily access and manipulate specific values like interface status or IP addresses. Which Python standard library module should be used for this purpose?
- Acsv
- Bxml.etree.ElementTree
- Cjson
- Dre
Show answer & explanationAnswer & explanation
Correct answer: C. json
The `json` module in Python's standard library provides functions for encoding and decoding JSON data. The `json.loads()` method can be used to parse a JSON string into a Python dictionary or list, making it easy to access and manipulate the data.
Why the other options are wrong
- A. The `csv` module is used for reading and writing CSV (Comma Separated Values) files, not JSON.
- B. xml.etree.ElementTree is used for parsing XML data, not JSON.
- D. The `re` module provides regular expression operations, not for parsing structured data formats like JSON.
Python json Module
A standard Python library module that provides methods for encoding Python objects into JSON format and decoding JSON data into Python objects.
- json.loads(): Decodes a JSON string to a Python object (dict/list).
- json.dumps(): Encodes a Python object to a JSON formatted string.
- Handles common JSON data types (strings, numbers, booleans, null, arrays, objects).
- Essential for interacting with RESTful APIs that use JSON.
Memory trick: For JSON, just call the 'json' module, it's already there for you.
