Question

Python. I need to assign multiple class instances to number of variables. First i tried this:

a = b = c = []

but they all refer to the same object, which is not what I need. This works better:

(a, b, c) = [[] for i in range(3)]

but it seems a bit too verbose. Is there a shorter way to do this?

UPDATE: OK, so this is not really Pythonic to cram everything into one line, question resolved.

But if this worked it’d be really cool:

a,b,c = []*3

And this line creates three references to the same object:

a,b,c = [[]] * 3

Oh well…

Answer 1

a, b, c = [], [], []
