No, think about it like

0 == False

if you do

True and False or False and True == False

you always get False

similar to that is

9 and 0 or 0 and 9 == 0

because 0 == False

shouldn't it also return 0 if n is anything elses than 9 ? (juste trying to understand it correctly)

why reverse it?

The [] lead to list comprehension which will actually create the array. Omitting [] is the same as replacing it by (). That is a generator expression, which does not construct the array first and should therefore be preferred.

wat? :O

damn... need to learn map asap

You are right, the brackets are not needed. Further, they are not wanted - the code would be better (clearer and more efficient) without them.

hmm, did sanme without list brakets. is it only for v3 or it didnot even need [] ?

damn T_T, did not know it worked that way

how the hell is "255.0.1.0" is valid IP ???? how can ip end in 0???

thx for reference!

Yeah, it's not the most readable code. Having trouble looking it over myself over a year later.

i'll go dig hole somewhere :/
