What is an avenue in a Karel world?

In a Karel world, an avenue refers to a column. This is a key part of Karel's grid layout, where the grid consists of streets running horizontally and avenues running vertically. When discussing Karel's environment, it is essential to understand that avenues help define the position of Karel and the objects within that vertical grid structure.

In the context of programming Karel's movements, recognizing that avenues are columns aids in writing commands for Karel to navigate through the grid efficiently. Understanding this spatial organization is crucial for solving challenges involving Karel's movements and tasks within the virtual environment. This foundational knowledge helps learners grasp how to manipulate Karel's position and interactions in the grid.
