If you're going to use brackets like that, I'd prefer a multi-character delimiter: [[[abcdef]]] But you have to be careful about the nesting, because that makes it difficult to create a string with an imbalanced set of delimiters. You'll end up with messy and complicated edge cases. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
