code: def _en_to_enth(energy, concs, A, B, C):
      """Converts an energy to an enthalpy.
  
      Converts energy to enthalpy using the following formula:
      Enthalpy = energy - (energy contribution from A) - (energy contribution from B) -
          (energy contribution from C)
      An absolute value is taken afterward for convenience.
  
      Parameters
      ----------
      energy : float
          The energy of the structure
      concs : list of floats
          The concentrations of each element
      A : float
          The energy of pure A
      B : float
          The energy of pure B
      C : float
          The energy of pure C
  
      Returns
      -------
      enth : float
         The enthalpy of formation.
