I know, and I just wanted to make it explicit for people who didn't know
much about Python regexes.

  Or,

def repeat_preceding( min=None, max=None, count=None ):
    return '{' + str( count )+ '}' if count else \
    '{' + str( min )+ ',' + str( max )+ '}'

digit = '[0-9]'
word_boundary = r'\b'
hyphen = '-'

my_regexp = word_boundary + \
digit + repeat_preceding( min=2, max=7 ) + hyphen + \
digit + repeat_preceding( count=2 ) + hyphen + \
digit + repeat_preceding( count=2 ) + word_boundary
