[QUOTE="Steven D'Aprano, post: 3703799"]
I can't see how this is any different between what we have now. Here's an 
example using keyword arguments:

# untested
"{modifier} {noun}".format(modifier="dead", noun="parrot")
"{noun} {modifier}".format(modifier="mort", noun="perroquet")

compared to:

"%(modifier)s %(noun)s" % dict(modifier="dead", noun="parrot")
"%(noun)s %(modifier)s" % dict(modifier="mort", noun="perroquet")

Whether using % or format(), I don't see the need to change the code, 
only the strings.

Using positional arguments is not really that different:

"{0} {1}".format("dead", "parrot")
"{0} {1}".format("perroquet", "mort")

versus:

"%s %s" % ("dead", "parrot")
"%s %s" % ("perroquet", "mort")

In this case, the template on the left remains the same, you just have to 
reorder the string arguments on the right. Clearly less satisfactory than 
the solution using keyword substitution, but whatever solution you pick, 
I don't see any advantage to format() over % formatting. Can you show an 
example?
