I think it's a typo. The function write_nexus_data takes an argument
"filename", and this code block is supposed to figure out whether that's an
open file handle or a file name.

So it should be:

if hasattr(filename, 'write'): ...

But we actually do it a different way now, checking for strings:

if isinstance(filename, basestr): # open it
else: # it's a handle
