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.
