💡 Hint

Common Mistakes

Using 'jsonify' which is for creating JSON responses, not reading JSON from requests.

Using 'json' which is a module, not a method on request.

Using 'get_data' which returns raw data, not parsed JSON.

The get_json() method extracts JSON data from the request body in Flask.

💡 Hint

Common Mistakes

Using dot notation which does not work on dictionaries.

Using parentheses which are for function calls.

Using curly braces which define dictionaries, not access keys.

JSON data parsed into a Python dictionary is accessed using square brackets [] with the key as a string.

💡 Hint

Common Mistakes

Using dot notation for nested keys.

Using parentheses which cause syntax errors.

Using curly braces which are for dictionary literals.

To access nested dictionary keys, use square brackets for each key step.

4fill in blank

hard

Fill both blanks to safely get the 'age' key from JSON data with a default of 0.

Flask

age = data.[1]("age", [2])

Drag options to blanks, or click blank then click option'

Aget

B0

CNone

Dpop

💡 Hint

Common Mistakes

Using 'pop' which removes the key from the dictionary.

Using 'None' as default which is not the intended default here.

Using dot notation without a method.

The get method retrieves a key's value or returns the default if the key is missing.

5fill in blank

hard

Fill all three blanks to create a Flask route that accepts JSON POST requests and returns the 'status' key.

Flask

from flask import Flask, request, jsonify

app = Flask(__name__)

@app.route('/status', methods=[[1]])
def get_status():
    data = request.[2]()
    status = data.get([3], 'unknown')
    return jsonify({'status': status})

Drag options to blanks, or click blank then click option'

A'POST'

Bget_json

C'status'

D'GET'

💡 Hint

Common Mistakes

Using 'GET' method which does not send JSON in the body.

Using 'jsonify' instead of 'get_json' to read data.

Using wrong key name or missing quotes.

The route must accept POST requests, use get_json() to get JSON data, and access the 'status' key.
