heroku - Setting Django secret key in environment variable fails due to special character -

I set a Django secret key in my venv / bin / activate .

But the key is "(" and I get a venv error : venv / bin / activate: line 85: syntax error near unexpected token) "

I got some stuck here. How can I set this key as a local environment variable so that it can accept these special characters?

A string around with double or double quotation marks. Now for the wire (multiple lines), you can use single or double quotation marks in sets of three. For more information and examples, see.
