Thanks! That seems like the fastest solution.
When looping through 1000000, I get these results:
ord : 4.703 (Terry Reedy)
divmod : 10.469 (Paul Rubin)
modulo : 7.625 (Roy Smith)
lst comp: 11.750
map : 9.062
str : 8.219
The modulo and divmod methods includes list.append(d) and
list.reverse() (list.append mapped to list_append).
