Can external libraries be used in Karel programming?

Karel programming is designed as a simplified programming environment primarily for educational purposes. It emphasizes learning fundamental programming concepts without the complexities that can arise from using external libraries. Thus, Karel's environment is typically self-contained, allowing students to focus on the basics of commands and control structures without the need for additional resources or tools.

While using external libraries might enhance some programming environments by adding more features or capabilities, Karel's introductory nature is best served by keeping the programming experience streamlined and focused on the core principles. This helps learners understand how programming works without the added complexity that comes with integrating external libraries.
