Hi All,
I know

But sum with [] 'empty list' as second parameter returns as below.

Can any one please explain this logic ? I searched in google but could not
find the suitable answer.
Thanks in advance.

[] + [1,2,3] + [3,4,5]
returns [1, 2, 3, 3, 4, 5].

That is clearly marked as "Python 3 Programming Tutorial". Why are you
