💡 Hint

Common Mistakes

Leaving out the slash causes Flask to redirect automatically, which might confuse beginners.

The trailing slash '/' in the route decorator means the URL must end with a slash. Flask will redirect '/home' to '/home/' automatically.

Complete the code to define a Flask route that responds to '/about' without a trailing slash.

Flask

from flask import Flask
app = Flask(__name__)

@app.route('/about[1]')
def about():
    return 'About Page'

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

💡 Hint

Common Mistakes

Adding a slash causes Flask to redirect '/about' to '/about/' which is not intended here.

When the route does not have a trailing slash, Flask will not redirect URLs with a slash to this route. The URL must match exactly '/about'.

Fix the error in the route decorator to correctly handle the URL '/contact/' with a trailing slash.

Flask

from flask import Flask
app = Flask(__name__)

@app.route('/contact[1]')
def contact():
    return 'Contact Us'

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

💡 Hint

Common Mistakes

Using double slashes or repeating the route name inside the decorator.

The route should end with a single '/' to indicate a trailing slash. Using '/contact/' twice or no slash causes errors or unexpected behavior.

Complete the code to create a Flask route that accepts '/profile' without a slash and '/profile/' with a slash, redirecting the slash version to the no-slash version.

Flask

from flask import Flask
app = Flask(__name__)

@app.route('/profile', strict_slashes=[1])
def profile():
    return 'User Profile'

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

DFalse

💡 Hint

Common Mistakes

Adding a slash in the route string or setting strict_slashes=False disables the redirect behavior.

Setting the route without a trailing slash and strict_slashes=True means Flask will redirect '/profile/' to '/profile'.

hard

Fill all three blanks to define a Flask route that accepts '/dashboard/' with a trailing slash and disables automatic redirect for missing slash URLs.

Flask

from flask import Flask
app = Flask(__name__)

@app.route('/dashboard[1]', strict_slashes=[2])
def dashboard():
    return 'Dashboard Page'

# Accessing '/dashboard' will [3] redirect to '/dashboard/'

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

BTrue

💡 Hint

Common Mistakes

Setting strict_slashes=True causes Flask to redirect automatically.

Using a trailing slash in the route and strict_slashes=False disables Flask's automatic redirect from '/dashboard' to '/dashboard/'.
