There are a (very) few cases where data structures require the
creation of cyclic references. One example I've used is in
managing comms networks where nodes are multiply and/or
cyclically linked and you n

Its Python's way of telling you that you have a
self referential data structure. Its just a
representational thing but without it Python
would end up printing an infinite sequence
of values.

No, you are confusing variable names with objects.
Here you only have one object - the number 5.
For a cycle you need at least 2 objects and those
objects must be able to reference another object.
