Complete the code to read the API version from the custom header.
version = request.headers.get('[1]')
The custom header X-API-Version is commonly used to specify the API version in header-based versioning.
Complete the code to check if the API version is 'v2'.
if version == '[1]': process_v2_request()
The version string is usually short and simple like v2 to indicate version 2.
Fix the error in the code to correctly extract the version from headers.
api_version = request.headers['[1]']
The correct header key is X-API-Version to get the version value.
Fill both blanks to create a response that varies based on the API version header.
if request.headers.get('[1]') == 'v1': return [2]('Response for version 1')
The header X-API-Version is checked, and jsonify is used to create a JSON response.
Fill all three blanks to implement header-based versioning with default fallback.
version = request.headers.get('[1]', '[2]') if version == 'v1': return [3]({'message': 'Version 1 response'})
The code reads the X-API-Version header with a default of v1, then returns a JSON response using jsonify.
