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.

Common mistakes
For define an instance method, keep the data shape and value types consistent with Method.
Keep every dependent statement inside the correct indented Python block.
Verify the final Method and Object state result against the sample before trying new data.
