PROGRAM EXPLANATION
Algorithm and explanation
- Initialize the sample values used to define an instance method.
- Define the class behavior for Method and apply Object state.
- Display the result for define an instance method and compare it with the documented sample output.
This example of define an instance method organizes the required state and behavior in a class. It demonstrates Method and Object state and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST
Common mistakes
Check this
For define an instance method, keep the data shape and value types consistent with Method.
Check this
Keep every dependent statement inside the correct indented Python block.
Check this
Verify the final Method and Object state result against the sample before trying new data.
Try it yourself
Practice: Run the program with the sample input, predict its output, and then test one boundary case of your own.
