#样例列表

    options=test_list,			#可选参数
    value=[test_list[0]],		#默认选项
    rows=6,						#显示行数
    description='产品代码：',	#描述信息
    disabled=False				#是否不可用
)
#提交按钮
submit_buttom = widgets.Button(
    description='提交',
    layout=Layout(width='30%', height='50px'),

#触发函数
def btn_click(sender):

#绑定触发函数
submit_buttom.on_click(btn_click)
#组件展示
display(productcode,submit_buttom)
