Actually, in recent Pythons (2.5 or better, I believe) the peephole
optimizer will do the concatenation at compile time even if you leave the
+ signs in, provided that the parts are all literals.
>>> from dis import dis
>>> dis(compile(r's = "a\n" + "b\n"', '', 'single'))
1 0 LOAD_CONST 3 ('a\nb\n')
3 STORE_NAME 0 (s)
6 LOAD_CONST 2 (None)
9 RETURN_VALUE
