[Tutor] global variables/constants versus volatile variables/constants

[diliup gabadamudalige]

Hi All!
Hope everyone is well.

In my code there are many dictionaries and lists which are used in various
functions. Is it better/pythonic/efficient to have these inside the
function itself or declared at the beginning of the program in which case
they will be global? They are all read only. I understand that global
constants and variable have memory allocated to them but when declared
inside a function are created on the fly, used and discarded. Please
enlighten me further on this and correct me if i'm wrong.

Thank you for your time and may you be well.
