Why is the order of multiple `for` list comprehension the way it is?

Question

I know the right way to have multiple for in a nested list comprehension is as follows (Python 3):

lista = [[[1,2],[3],[4,5,6]],[[7],[8,9]]]

Answer 1

Just remember the famous line from Casablanca: "Of all the gin joints in all the towns in all the world..." And then remember that the Python equivalent is backwards from that.

[ginjoint for town in world for ginjoint in town] 

Because who wants their programming language to sound like the greatest movie of all time?
