Answer 3

Referencing the Python Documentation:
- https://docs.python.org/2/library/functions.html#id

id(object)
--------------
Return the “identity” of an object. This is an integer (or long integer) which is guaranteed to be unique and constant for this object during its lifetime. Two objects with non-overlapping lifetimes may have the same id() value.

CPython implementation detail: This is the address of the object in memory.

Answer 4

Given that the question is in Python, it doesn't necessarily have anything to do with CSS/HTML.
I.E. It could have something to do with a user id.
Can you post the code?

Answer 5

It's exactly as @Nithiwat, @David, and @James have all posted.
https://docs.python.org/3.6/library/functions.html#id
It just returns a unique integer id number for that python object.
