unpack

[Date Prev][Date Next][Thread Prev][Thread Next] [Date Index] [Thread Index]


Hi,
I was puzzled by the results of unpack, below
> x = {'a', 'b', 'c', 'd', 'e'}
> y = {'v', 'w', 'x', 'y', 'z'}
> print(unpack(x), unpack(y))
--> a v w x y z
Since unpack returns all the table elements, I was expecting to see 
a b c d e v w x y z
Is there a simple explanation of the principle at work here?
Thanks!
