Add test script to validate Python client generation for PetstoreAdd python client test script

[Gosling-dude]

Description

Added a test script test_script.py under samples/client/petstore/python/ to:

• Validate that the generated Python client builds successfully.
• Ensure the client modules can be imported.
• Confirm that the DefaultApi class instance can be created.

This makes it easier to confirm that the Python SDK generated from the Petstore spec is functional and can be used as a reference for users.

Related Area

• Language: Python
• Location: samples/client/petstore/python/

Checklist

• Generated the client using the latest code
• Tested the client locally
• Confirmed that imports and class instantiation work

are you using an old version of openapi generator?

samples/client/petstore/python/ doesn't exist in the latest version

(python client generator was refactored in v7.x)

Thanks for the feedback, @wing328 !

You're right — this script was based on an older version of the project structure. I'll rebase my branch onto the latest master and update the script path to align with the refactored Python client generator in v7.x. Will push the changes shortly!
