Just to send my 2 cents more:
tuple creation vs list creation may be significant depending on what it
contains.
and O(n) is definitely O(n)...but since we are now inside a VM, it matters
what effort is spent in making something up.
what do you think of code snippet:
>>> def l():
... l = [1,2,

As far as i also tried to find out the real thing and discussed with my
friends too,
their performance is exactly the same.
*'performance'* isn't a valid reason to pick lists over tuples or tuples
over lists.
A list is a resizable, mutable sequence; a tuple is an immutable sequence
