code: def euclidean(src, tar, qval=2, normalized=False, alphabet=None):
      
      return Euclidean().dist_abs(src, tar, qval, normalized, alphabet)
docs: Return the Euclidean distance between two strings.
  
      This is a wrapper for :py:meth:`Euclidean.dist_abs`.
  
      Parameters
      ----------
      src : str
          Source string (or QGrams/Counter objects) for comparison
      tar : str
          Target string (or QGrams/Counter objects) for comparison
      qval : int
          The length of each q-gram; 0 for non-q-gram version
      normalized : bool
          Normalizes to [0, 1] if True
      alphabet : collection or int
          The values or size of the alphabet
  
      Returns
      -------
      float: The Euclidean distance
