I was just at a point when I thought I learned something but got
confused again after trying the following and unfortunately didn't
find an answer in the docs.

>>> a = 10
>>> b = 10
>>> id(a)
134536516
>>> id(b)
134536516

So the two memory addesses are the same, but

>>> a = 10000
>>> b = 10000
>>> id(a)
134604216
>>> id(b)
134604252

and they are not the same (I restarted the interpreter between the two
cases). So how is this now? Sorry if it's too trivial, but I simply
don't get it.
