Select + Add from the top menu and then Add role assignment from the resulting drop-down menu. So my idea is to set up event listeners on both ends: on the remote side, create a python package that once imported and activated, will automatically collect graphs whenever one is rendered, and when the main python program exits (either naturally or because of bug), it will then create a pdf out of the plots stored, and save it in a folder in the drive. An event handler is a function that is executed when an event is triggered on a web page. Events are a great way of telling multiple objects (listeners) that a certain event of their interest has occurred without having to search for them; its computationally efficient and really dynamic. If this is a file-like object, is has to opened in text channel (int) Default channel to log as if not specified by the interface. Python 2.7 ( https://www.python.org/downloads/ ) Event listeners are a set of functions in a selenium python bindings that waits for an event to occur; that event may be a user clicking or finding, changing the value, or an Exception.
