The Python3+ Tkinter implementation of the “push box” code is simple for beginners to learn Python

Push the box is a puzzle game, in childhood we have played

Today, Python implements one of its own, using Python3+ Tkinter (the built-in module), which checks the keyboard movement and controls the position of the character

The running effect is as follows:

The complete code is as follows: (material download address: www.itprojects.cn/detail.html…).

from tkinter import *
from tkinter.messagebox import *
import copy

root = Tk()
root.title("For more on pushing boxes visit www.itprojects.cn")
