What is a street in a Karel world?

In a Karel world, a street is defined as a row across which Karel can move. This is a fundamental concept in understanding Karel’s environment, as it allows the robot to navigate horizontally through the grid-like layout of the world. The rows are critical for Karel to perform tasks and to interact with beepers or obstacles positioned on the grid.

Understanding this concept is important for programming Karel effectively, as it will involve moving up and down these rows to manipulate objects and execute commands. The concept of a column, avenue, or path may refer to different aspects of the grid that Karel navigates, but in the context of this question, "row" specifically refers to the horizontal traversal locations in the world where Karel operates.
