[ase-users] writing lammps-data and python 3.7

[Noam Bernstein]

Has anyone tried writing lammps-data file with python 3.7?  Before I open an issue, I'm trying to understand if I'm just missing something.  I get the error 
TypeError: write() argument must be str, not bytes
which the internet suggests is caused by the file object not being opened with "wb".  Poking around ase.io <http://ase.io/> I get the impression that it's being specifically opened with "wt".  

Does anyone know that code and have any idea whether this is a python issue or a genuine ASE bug?
