As all your imports are from the same module a.py, isort is sorting them alphabetically, with precedence given to capital letters. By default, isort also separates aliased imports (as) from regular ones. That’s why you're seeing three distinct import blocks:

1. Imports that come before Conversation alphabetically.
2. The import with an alias: Conversation as APIConversation.
3. Imports that come after Conversation alphabetically.

If you want to group them all into a single block, you can set:

combine_as_imports = true

in your isort configuration.

Also, the command you're using appears to be incorrect, make sure to define the profile isort should use (e.g., --profile black). You can find more details in the isort documentation.

Hope this will help you.
