What happens when two lists are compared in Python?

Question

I have two lists which contain some numbers, different in each list. What happens when I compare them using < or >?

Answer 1

Lexographical comparison would occur, much like how strings are compared, or how terms are ordered in a dictionary. For instance,

[1,2,3] > [1,2,2] #true
[1,2,3] > [1,2,2,4] #true
[1,2] > [1,2,3] #false

Answer 2

a or b will return

- a if list a is not empty
- b if list a is empty and list b isn't
- [] if both list a and list b are empty
