Common Mistakes

Using a different name than the variable name causes confusion.

Leaving the name blank or misspelled.

The blueprint name should be 'auth' to match the variable name and purpose.

💡 Hint

Common Mistakes

Using a non-existent method like 'add_blueprint'.

Forgetting to register the blueprint causes routes not to work.

Use register_blueprint to add a blueprint to the Flask app.

💡 Hint

Common Mistakes

Using a function name unrelated to the route can confuse readers.

Leaving the function name blank or using reserved words.

The function name should match the route handler, here 'hello' matches the route '/hello'.

4fill in blank

hard

Fill both blanks to create a blueprint with a URL prefix and import it in the app.

Flask

from flask import Flask
from [1] import auth

app = Flask(__name__)
app.[2](auth, url_prefix='/auth')

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

💡 Hint

Common Mistakes

Using wrong module names or method names.

Forgetting the URL prefix when registering the blueprint.

Import the blueprint from the module named 'blueprints' and register it with register_blueprint.

5fill in blank

hard

Fill all three blanks to define a blueprint, add a route, and register it with the app.

Flask

from flask import Flask, Blueprint

app = Flask(__name__)

api = Blueprint('[1]', __name__)

@api.route('/status')
def [2]():
    return 'API is running'

app.[3](api, url_prefix='/api')

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

💡 Hint

Common Mistakes

Using inconsistent names for blueprint and variable.

Using wrong method to register the blueprint.

Naming the route function unrelated to the route.

The blueprint is named 'api', the route function is 'status', and the blueprint is registered with register_blueprint.
