💡 Hint

Common Mistakes

Using a key that is not present in the query parameters.

Using a key that is too long or uncommon.

The standard query parameter key for versioning is often version.

2fill in blank

medium

💡 Hint

Common Mistakes

Using assignment operator = instead of comparison.

Using inequality operator != by mistake.

To check equality, use the == operator.

3fill in blank

hard

Fix the error in the code to return a JSON response with the version.

Rest API

return jsonify({'version': [1])

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

Arequest.args.get('version')

Bversion()

Cversion

D'version'

💡 Hint

Common Mistakes

Using version() which causes an error because version is not a function.

Using a string literal 'version' instead of the variable.

The variable version holds the version string and should be used directly.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps endpoints to their versions if version is greater than '1'.

Rest API

versions = {endpoint: [1] for endpoint, [2] in endpoints.items() if version > '1'}

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

Aversion

Bver

💡 Hint

Common Mistakes

Using inconsistent variable names for the value in the comprehension.

Using a variable name not defined in the loop.

The dictionary comprehension uses version as the value and version as the variable for the value in the loop.

5fill in blank

hard

Fill both blanks to filter endpoints with version '2' and create a dictionary with uppercase keys.

Rest API

filtered = {endpoint.[1](): version for endpoint, version in endpoints.items() if version [2] '2'}

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

A{

C==

D[

💡 Hint

Common Mistakes

Starting comprehension with square brackets instead of curly braces.

Using wrong comparison operator for filtering.

The dictionary comprehension starts with {, uses upper() to uppercase keys, and filters with ==.
