Thanks for the code . I am Getting Error "TypeError: can only concatenate tuple (not "list") to tuple"

trace3['x'] += [x0, x1, None]
    trace3['y'] += [y0, y1, None]
    
    trace3_list.append(trace3)

    middle_node_trace['x'].append((x0+x1)/2)
    middle_node_trace['y'].append((y0+y1)/2)
    # middle_node_trace['text'].append(str(edge[2]['weight']))
    middle_node_trace['text'].append(str(1))
