I want to fix an error in some code I have installed, however I don't really want to just bodge it.
The function producing the error is:- def get_text(self, idx): # override ! node = self.items[idx] a= [ ", ".join(node.tags), node.comment, node.folderName, cd2rd(node.date), node.name, '[' + self.rating_stars[node.rating] + ']' ] [self.select] return a The error occurs when node[] (or at least its members) turn out to be empty, you get a Traceback that ends with:- File "/usr/lib/jbrout/jbrout/listview.py", line 608, in draw_cell layout.set_text(self.get_text(thumbnail_num)) File "/usr/lib/jbrout/jbrout.py", line 325, in get_text ", ".join(node.tags), TypeError: sequence item 0: expected string, NoneType found Now its *probably* something higher up the tree causing the problem (it's only one particular image in 20 thousand or so that breaks things) but I really want to just get things working. So, what's the neatest way to protect the get_text() method from empty data? -- Chris Green -- http://mail.python.org/mailman/listinfo/python-list
