Use Python's implicit string concatenation:

some_message = ("This is a really long line "
                 "of text that Python automatically "
                 "joins into a single string.")


The advantage of implicit concatenation is that it is guaranteed to
happen at compile-time, while the + operator may or may not occur until
run-time, depending on the version of Python.
