triggered syntax - Another solution would be to provide a more ergonomic

triggered_id = callback_context.triggered[0]['prop_id']

For example, we could make a new triggered_dict that would have the same content but be a dictionary instead of a list. The logic would become:

def update_graph(b1, b2):
    if 'reset.n_clicks' in dash.callback_context.triggered_map:
        return reset_graph()
    elif 'draw.n_clicks'  in dash.callback_context.triggered_map:
        return draw_graph()

which would save another line of code.

I can’t believe I missed this gem in @chriddyp original post, but I’d like to give it and a

I think making a new triggered dict would make the code so much more readable. To me, this is meaningless boilerplate:

triggered_id = callback_context.triggered[0]['prop_id']
