Under the 3rd step in this exercise, the following statement has been written:
current_vertex is the string .value property of a Vertex instance held within Graph . Inside the loop, print current_vertex .
I’m finding it hard to grasp what it’s trying to tell. Much appreciated for the elaboration:O

This step is early in the process of developing a search algorithm. They are just pointing out for future reference that the variable current_vertex is a string, which is the station name in English. That name also happens to be the .value attribute of a vertex instance, so peel_station.value = "peel".

But in this particular step, you needn’t worry about that. All you really need to do is pop current_vertex from a list and print it.

Why does the lesson recommend using .pop(), when it causes an error to display on the terminal? I tried using .remove(), and it works much better.
