💡 Hint

Common Mistakes

Using GET instead of HEAD in the condition.

HEAD requests require the body to be empty but headers to be present.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps HTTP methods to their descriptions for OPTIONS response.

Rest API

methods_info = {method: '[1]' for method in ['GET', 'POST', 'HEAD', 'OPTIONS'] if method [2] 'OPTIONS'}

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

💡 Hint

Common Mistakes

Using '==' instead of '!=' in the condition.

This comprehension maps methods except OPTIONS to the string 'supported'.

5fill in blank

hard

Fill all three blanks to build a response dictionary for OPTIONS method with method names, descriptions, and a flag.

Rest API

response = {
    '[1]': [method for method in allowed_methods],
    '[2]': {method: '[3]' for method in allowed_methods}
}

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

💡 Hint

Common Mistakes

Using incorrect keys that don't match the response structure.

The response includes a list of methods and a dictionary of descriptions labeled 'supported'.
