This function replace {} for arguments received. You just need 
don't send {} as arguments.
I tested native function format() in Python:
print("Helo {} {}".format("{}", "name")) # Helo {} name
Nothing wrong, working same way.
Works with index too.

     writeln("Hi, my name is {1} and I live in 
{0}.".format("Brasil", "Marcone"));
  	writeln("Hi, my name is {} and I live in {}.".format("Marcone", 
"Brasil"));
