💡 Hint

Common Mistakes

Using request.args which is for URL parameters.

Using request.json which is for JSON payloads.

The request.form dictionary contains form data sent via POST method.

4fill in blank

form_data = [1]: request.form[[2]] for [1] in request.form}}

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

Bvalue

Ckey

Ditem

💡 Hint

Common Mistakes

Using different variable names for the key and the loop variable.

Using a variable name that does not match the loop variable.

The comprehension iterates over form field names, using each as the key and accessing its value.

5fill in blank

hard

Fill all three blanks to safely get a form value with a default fallback.

Flask

username = request.form.get([1], [2]) if request.method == [3] else None

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

A'username'

B'guest'

C'POST'

D'GET'

Attempts:

💡 Hint

Common Mistakes

Using the wrong HTTP method string in the condition.

Not providing a default value in get(), which can cause errors.

This code gets the 'username' from the form if the method is POST; otherwise, it sets username to None. It uses 'guest' as a default if the field is missing.
