-1. The feature exists to allow adherence to PEP-8, "Limit all lines to a maximum of 79 characters.", without requiring runtime concatenation costs. I use it frequently when assembling and testing message strings, for instance.

In many cases there is no runtime concatenation cost.

def f(): ... return "first" + "second" ... import dis dis.dis(f) 2 0 LOAD_CONST 3 ('firstsecond') 3 RETURN_VALUE
