Hello ase users

I am trying  to make an hcp structure of lanthanum oxide(la2o3) by using
HexagonalClosedPacked tag from ase.lattice.hexagonal module. For which the
command line I am using is

>>>la2o3 = HexagonalClosedPacked(symbol=('La', 'O'),
latticeconstant={'a':3.94, 'c/a':1.56, 'alpha':90, 'beta':90, 'gamma':120})

This will gives me an error

TypeError: The symbol argument must be a string or an atomic number.

Any help regarding this is appreciated.

Thank You
