Are you worried about translators? The gettext functions themselves will just see the result of the operation. The extraction tools like xgettext do fail, however. Translating the above to

The problem is that

 gettext("some string"
   " and more of it")

is not the same as

 gettext("some string" +
   " and more of it")

and invoking "xgettext --force-po --language=Python test.py" gives

BTW, it doesn't work for the C equivalent, either.

You would either have to teach pygettext and maybe gettext about this construct, or you'd have to use something different.

Teaching Python-based extraction tools about it isn't hard, just make sure that you slurp in the whole argument, and eval it. If what you get isn't a string, throw an exception. xgettext will be harder, since apparently does not do it, nor does it even know enough to error or warn on syntax it doesn't handle within gettext()'s argument.
