'str' has no attribute 'iteritems'

[gernophil]

For some ENST numbers and HGNC we run into the error AttributeError: 'str' object has no attribute 'iteritems' (whole error at the bottom). This happens because sometimes the edit_map becomes an empty string. I tried to follow the script, but I can't see where this happens, since the function get_edits always gets an empty dictfor edit_maps and just adds entries. I could dodge this error by adding the line if not isinstance(edit_map, str): between the lines 518 and 519. It works with this edit and get_snps should only return empty lists in this case, but I am not sure, if the results would still be correct. Do you see, why this happens and can you maybe evaluate, if my solution is reasonable?

That sounds like it could work.
