CPython is interning small integers and small strings as a form of optimisation.

"The current implementation keeps an array of integer objects for all
integers between -5 and 256, when you create an int in that range you
actually just get back a reference to the existing object."

For integers see https://docs.python.org/2/c-api/int.html for Python 2
or https://docs.python.org/3/c-api/long.html for Python 3.

For strings see https://hg.python.org/cpython/file/3.5/Objects/codeobject.c#l51
