如何在Bokeh仪表板中显示和更新打印语句列表？

from bokeh.models import Div
from bokeh.layouts import column
from bokeh.io import curdoc

print_div = Div(text="")

print_statements = []

def update_print_statements():
    print_div.text = "<br>".join(print_statements)

print_statements.append("要打印的语句")
update_print_statements()

layout = column(print_div)

curdoc().add_root(layout)
