With your format() call, you need a string format specifier to tell it how
to use the arguments you've supplied it..for example, in the working script
one, the format specifier is the string "{0}_JY_{1}"
If you did a straight print on this, you'd get literally "{0}_JY_{1}", but
since you're invoking format() against it, it'll go through and replace the
{0} with the first argument in format() and {1} with the 2nd argument, and
so on and so on. The { } are markers for where format() should be inserting
values. Your loop currently is calling format(t[0], t[1]) against a string
that doesn't contain any of the { }'s so it's not doing anything, and the
result is that new_fn is the same as objects
Is this more what you're after?
list = cmds.ls('*_set*')
for objects in list:
# t = cmds.ls(objects)[0].split('_')[-1]
# no need to call cmds.ls again to select anything, you've
# already got the name with the first cmds.ls('*_set*') call
t = objects.split('_')[-1]
# new_fn = objects.format( t[0], t[1] )
# apply a new prefix to the setXYZ suffix
new_fn = "aNewPrefix_{0}".format(t)
