file manage py line 17 from exc django

The line "from exc django" in a Django file is not a valid Python syntax. It seems to be a typographical error or a misunderstanding. The correct usage to import the Django module in a file would be "import django" or "from django import something" where "something" is a specific module or class within the Django package. If there's a specific error or issue related to this line, please provide more context or details about the problem for further assistance.
