Idk... if it's all tabs v for visual mode, select text :%s/\t/ /g boom selected text to PEP8 standard from tabs same if it's spaced otherwise evenly (Interpreter will give you a hard time if it isn't and won't execute the script, so what even is it if not that). your tabstop settings set to this should be fine for the << >> method. It's really not that hard?
