I do not know ConfigParser. You should show us the code so we can see what's 
wrong.
What API call do you look for? What is your exact goal?

That's an error from Python. It appears that the dictionary got screwed up.
See that the inner dict in '802-1x' is erroneosly in quotes ('802-1x': 
"{...}") and thus it doesn't match sa{sv} signature, which is what the error 
probably says.
