Parameter type converters (int, float, path) in Flask - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a route that accepts an integer parameter named <user_id>.

Flask

from flask import Flask
app = Flask(__name__)

@app.route('/user/[1]')
def show_user(user_id):
    return f"User ID is {user_id}"

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

A<int:user_id>

B<string:user_id>

C<float:user_id>

D<path:user_id>

💡 Hint

Common Mistakes

Using will treat the parameter as text, not an integer.

Forgetting the converter and just using treats it as a string.

Using tells Flask to convert the URL part to an integer before passing it to the function.

2fill in blank

medium

Complete the code to define a route that accepts a floating-point number parameter named <price>.

Flask

from flask import Flask
app = Flask(__name__)

@app.route('/price/[1]')
def show_price(price):
    return f"Price is {price}"

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

A<path:price>

B<int:price>

C<float:price>

D<string:price>

💡 Hint

Common Mistakes

Using will cause errors if the URL has decimals.

Using treats the parameter as text.

The <float:price> converter converts the URL part to a floating-point number.

3fill in blank

hard

Fix the error in the route to accept a file path parameter named <filepath> that can include slashes.

Flask

from flask import Flask
app = Flask(__name__)

@app.route('/files/[1]')
def show_file(filepath):
    return f"File path is {filepath}"

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

A<path:filepath>

B<int:filepath>

C<string:filepath>

D<float:filepath>

💡 Hint

Common Mistakes

Using stops at the first slash, so the path is incomplete.

Using or causes type errors.

The <path:filepath> converter allows slashes in the parameter, capturing the full path.

4fill in blank

hard

Fill both blanks to create a route that accepts an integer <post_id> and a path <filename>.

Flask

from flask import Flask
app = Flask(__name__)

@app.route('/post/[1]/file/[2]')
def show_post_file(post_id, filename):
    return f"Post {post_id}, File {filename}"

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

A<int:post_id>

B<string:filename>

C<path:filename>

D<float:post_id>

Attempts:

3 left

💡 Hint

Common Mistakes

Using will not capture slashes in the filename.

Using is incorrect if the ID is an integer.

The first blank uses <int:post_id> to get an integer post ID. The second uses <path:filename> to accept a file path with slashes.

5fill in blank

hard

Fill all three blanks to create a route that accepts a float <rating>, an int <item_id>, and a path <image_path>.

Flask

from flask import Flask
app = Flask(__name__)

@app.route('/rate/[1]/item/[2]/image/[3]')
def show_rating(rating, item_id, image_path):
    return f"Rating: {rating}, Item: {item_id}, Image: {image_path}"

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

A<string:image_path>

B<int:item_id>

C<path:image_path>

D<float:rating>

Attempts:

3 left

💡 Hint

Common Mistakes

Using will not capture slashes.

Mixing up the order of converters causes errors.

The route uses <float:rating> for decimal ratings, <int:item_id> for integer item IDs, and <path:image_path> to accept image paths with slashes.
