[basex-talk] Handling exceptions in the Python Client API

I am now happily using BaseX from Jupyter Notebooks for Greek data - see these links: http://jonathanrobie.biblicalhumanities.org/blog/2017/12/08/jupyter-tutorial... http://jonathanrobie.biblicalhumanities.org/assets/greeksyntax-tutorial-proi... But I need to know how to handle exceptions, e.g. if the notebook user writes a query with an error in it. And I would also like to return some result if the query returns an empty sequence. Here is the current code: https://github.com/biblicalhumanities/greek-new-testament/blob/master/labnot... How can I improve what I am doing? Jonathan
