Zip with sequences of diffrent length

[Nickolay Kolev]

Hi all,

I want to make tuples of the elements of a list like this.

l = [1, 2, 3]

Wanted tuples:

(1, 2)
(2, 3)
(3, None)

I can get the first two tuples using zip(l, l[1:]). How do I get the
last one?

Many thanks in advance,
Nicky

Use map( None, l, l[1:] )

HTH,
Mike

>>> l = [1, 2, 3]
>>> zip(l, l[1:]+[None])

[(1, 2), (2, 3), (3, None)]
