id() gives you memory address of the variable.in python when you create something variable , function,object or whatever everything stores in memory block.each of variable,function has different memory block which can acess using using it's memory address.
x=5
print(id(x)) gives you memory address of the x variable.

Answer 2

it gives an specific id to an object for identification.

Answer 3

After experimenting, my observation is that
id(n+1) - id(n) = 16

Answer 4

When I redefine A from 3 to 4
its id increases by 16
So I'm not so sure about "specific id" or "memory address"
Looks like it's more about the value itself.
