Yes, I don't particularly see the advantage of writing:

"spam %s spam" % (value,) over "spam %s spam" % value Why require the first version?

Because the second breaks if value is a tuple:

Python 2.5 (r25:51908, Sep 19 2006, 09:52:17) [MSC v.1310 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information.

value = (1,2) "spam %s spam" % value Traceback (most recent call last): File "", line 1, in TypeError: not all arguments converted during string formatting
