Which of the following is an example of a technical skill relevant to computer programming?

Proficiency in Python or Java is a prime example of a technical skill relevant to computer programming because it directly relates to the ability to write, understand, and implement code within these specific programming languages. Mastery of programming languages involves a range of technical expertise, including understanding syntax, programming logic, and best practices for software development. These competencies are essential for creating applications, debugging existing code, and optimizing performance.

The other choices relate to soft skills or interpersonal abilities, which, while important in a work environment, do not directly pertain to the technical aspects of programming itself. Effective negotiation skills focus on communication and agreement between parties, team collaboration abilities emphasize working effectively within teams, and creative problem-solving pertains to generating innovative solutions to challenges, none of which are specific technical skills involved in the actual process of coding or software development.
