Solve the following python programming problem given the following code:
@ staticmethod 
def _sort_locations(locations, expand_dir = False) : 
    '
        Sort locations into "files" (archives) and "urls", and return
        a pair of lists (files,urls)
        ' 
    files = [] 
    urls = [] 
    def sort_path(path) : 
        url = path_to_url (path) 
        if (mimetypes.guess_type (url, strict = False) [0] == 'text/html') : 
            urls.append (url) 
else : 
            files.append (url) 
for url in locations : 
        is_local_path = os.path.exists (url) 
        is_file_url = url.startswith ('file:') 
        if (is_local_path or is_file_url) : 
            if is_local_path : 
                path = url 
else : 
                path = url_to_path (url) 
if os.path.isdir (path) : 
                if expand_dir : 
                    path = os.path.realpath (path) 
                    for item in os.listdir (path) : 
                        sort_path (os.path.join (path, item)) 
else : 
                    if is_file_url : 
                        urls.append (url) 
else : 
                if os.path.isfile (path) : 
                    sort_path (path) 
else : 
            urls.append (url) 
return (expand_dir, urls)
