PROGRAM EXPLANATION
Algorithm and explanation
- Import the required standard-library tools and prepare the sample data for create a data class.
- Define the class behavior for dataclass and apply Type annotation.
- Display the result for create a data class and compare it with the documented sample output.
This example of create a data class organizes the required state and behavior in a class. It demonstrates dataclass and Type annotation and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST
Common mistakes
For create a data class, keep the data shape and value types consistent with dataclass.
Keep every dependent statement inside the correct indented Python block.
Verify the final dataclass and Type annotation result against the sample before trying new data.
