That looks *a* *lot* like homework, so you're supposed to find the answer 
yourself. A few hints:

- splicing the digits will become easier if you convert the numbers to 
strings first.

- have a look at itertools.zip_longest() (you'll need to specify a 
fillvalue. Which?)

- you can build a string from a sequence of strings with "".join(strings).

If that's not enough to get a working solution you may come back here once 
you have some code.
