code: def fmtdeglon (radians, norm='wrap', precision=2, seps='::'):
      
      return _fmtsexagesimal (radians * R2D, norm, 360, seps, precision=precision)
docs: Format a longitudinal angle as sexagesimal degrees in a string.
  
      Arguments are:
  
      radians
        The angle, in radians.
      norm (default "wrap")
        The normalization mode, used for angles outside of the standard range
        of 0 to 2π. If "none", the value is formatted ignoring any potential
        problems. If "wrap", it is wrapped to lie within the standard range.
        If "raise", a :exc:`ValueError` is raised.
      precision (default 2)
        The number of decimal places in the "arcseconds" place to use in the
        formatted string.
      seps (default "::")
        A two- or three-item iterable, used to separate the degrees, arcminutes,
        and arcseconds components. If a third element is present, it appears
        after the arcseconds component. Specifying "dms" yields something like
        "12d34m56s"; specifying ``['', '']`` yields something like "123456".
  
      Returns a string.
