I am sorry I am a beginner at python and I was reading
my book and I came across the terms Nodes and Queue.
I am sorry but I don't quite understand how they work.
Its a bit of Comp Science terminology.
A Queue is a particular type of data structure somewhat
like a Python list but usually implemented in other
languages using a series of Node objects each of
which holds a value and a link to the next Node. You
then add values to the queue by creating a new
Node and linking it to the existing queue.
In Python you would usually implement a queue using
the standard list and use its pop/push methods and
indexing to simulate the behaviour without the hassle
of creating Node classes etc.
It suggests your book is a comp science oriented book
that happens to use Python rather than a dedicated
Python tutorial. (That is not necessarily a bad thing,
it will better prepare you for learning other languages
in the future)
