What is a street in a Karel world?

In Karel programming, a street refers to a row in the grid-like environment where Karel operates. Karel navigates this grid, which is made up of streets and avenues, somewhat analogous to a city layout. Each street consists of a series of units that Karel can move through and perform actions within.

Understanding that streets are essentially horizontal rows helps to clarify Karel's movement mechanics: Karel can move forward or turn to navigate these streets, collect beepers, or place them in designated locations. The distinction between streets and avenues in Karel's world is crucial since it defines the grid system in which Karel interacts, allowing students to better grasp the foundational concepts of spatial navigation and programming logic in Karel robotics.
