R. David Murray <[email protected]> added the comment:
No, because my code is a backward compatibility hack. Currently if someone is
passing a default successfully they must be doing it by passing in a list or
tuple consisting of one or more strings. So your code would result in
something like:
>>> ', '.join([str(['abc'])])
"['abc']"
However, you are correct that if default is some object other than a list, it
is either going to work in the ', ' or it isn't, so there's no need to call
list on it. So my code should be simplified to:
if isinstance(default, string):
default = [default]
return ', '.join(self.headers_get_all(name, default))
