Final answer:
A code of ethics is important for a profession because it sets the standards of behavior and conduct expected from professionals and ensures they act ethically and responsibly.
Step-by-step explanation:
A code of ethics is important for a profession because it sets the standards of behavior and conduct expected from professionals in that field. It helps ensure that professionals act ethically and responsibly, both in their interactions with clients or customers and in their decision-making processes. For example, in the field of software engineering, the Software Engineering Code of Ethics and Professional Practice defines the ethical obligations of software engineers, such as ensuring software safety and not compromising privacy. Without a code of ethics, professionals may act in ways that are unethical or harmful to others.
