A simple function that will remove the quote marks from every string in a list - if and only if the quote marks are the first and last character of the string, regardless of whether they are single or double quotes.
Useful when parsing the arguments of a custom tag.

"Given a list, will return a list with any leading and trailing quotes from the items in the list removed"
return [ ( arg[1:-1] if arg[0] == arg[-1] and arg[0] in ('"', "'") else arg ) for arg in args ]
