[link removed by admin]

[tidypy]

Research indicates: "try to use the split() method, on a list object instead of a string." I have the same issue. Workarounds tried: "adding attributes in properties", Running as Admin, Changing file Permissions, Tried various files and filetypes.

Code change required.

[cdgriffith]

Should be fixed as of 5.7.0!
