By omitting the positional specifiers it pushes the Python requirement to 2.7+ (right now the docs state 2.4+).
See: https://docs.python.org/2/library/string.html#format-string-syntax "Changed in version 2.7: The positional argument specifiers can be omitted, so '{} {}' is equivalent to '{0} {1}'."
