‘壹’ 如何使用python3自带的tkinter生成气泡提示

可以参考这个：

‘贰’ Python3 tkinter，怎么在Label/Canvas中插入图片

tkinter基于tcl/tk，只支持gif、png和bitmap位图，其余图片格式需要通过第三方库PIL（pillow）提供的ImageTk转化为tcl/tk能够接受的图片数据。

‘叁’ python3的tkinter代码，为什么会报错

1、可能是数据类型错误，int()接收到一个字符型。或是接收到的是一个浮点型。浮点型需要先转换。
比如int(10.0)需要改成int(float(10.0))。
2、可能是代码写错了，比如少打了个引号
