   A note about format strings: Python supports format strings with
unnamed arguments, such as ‘'...%d...'’, and format strings with named
arguments, such as ‘'...%(ident)d...'’.  The latter are preferable for
internationalized programs, for two reasons:

   • When a format string takes more than one argument, the translator
     can provide a translation that uses the arguments in a different
     order, if the format string uses named arguments.  For example, the
     translator can reformulate
          "'%(volume)s' has only %(freespace)d bytes free."
     to
          "Only %(freespace)d bytes free on '%(volume)s'."
     Additionally, the identifiers also provide some context to the
     translator.

   • In the context of plural forms, the format string used for the
     singular form does not use the numeric argument in many languages.
     Even in English, one prefers to write ‘"one hour"’ instead of ‘"1
     hour"’.  Omitting individual arguments from format strings like
     this is only possible with the named argument syntax.  (With
     unnamed arguments, Python – unlike C – verifies that the format
     string uses all supplied arguments.)
