It's not exactly the same in that it doesn't change values in
place, but this is similar if you are only interested in the
values:

ta = [t>=10 and t-10 or t+10 for t in ta]

(this rebinds ta, so if you had a former reference to ta, it
won't be changed by this code).

In general, I don't think in-place operations are in the
domain of list comprehensions, since they are expressions.
I might be able to mangle something into doing it, but it's
probably a bad idea anyway. I think your loop is stylistically
fine as is (if you need to change the list in place).
