I've been studying recently Python Of tkinter Of gui library , So I decided to make a gui Version of the student management system program
The original code is ：https://blog.csdn.net/weixin_43321726/article/details/103569640
This is my code , It took half a day to knock it out

canvas.create_image(700, 500, image=photo)
canvas.pack()
canvas.create_text(600,350,text=' huan To meet send use learn raw Letter Rest tube The reason is system system ',font=(' Microsoft YaHei ',26))
