[melbourne-pug] string formatting / Format SPecific Mini Language

[Javier Candeira]

You need two steps of formatting:

>>> string_length = 35
>>> format_string = "{something:<%d}" % string_length
>>> format_string
'{something:<35}'
>>> some_string = (format_string.format(something="somethingelse"))
>>> some_string
'somethingelse                      '
>>>
