Requirements

1. Run the code in console using command line.
2. It'll open a Python window to play the 2048 game.

What can we practice in this project?

• Turtle
• 2D List

A reference code

from turtle import *
from random import randint

title("2048")
gz = 176  # shapesize=8是连长160的正方形，我们可以将格子设置为162，这边就可以画出边框线
N = 4
bc = gz * N  # 边长
tracer(False)  # 不显示绘制动画
bgcolor("gray")
ht()
up()
speed(0)
shape("square")
shapesize(8)  # shapesize为8是一个连长为160的正方形

# 二维列表对应游戏表格

Run the demo

Please save the Python as game.py and run it in console：

python game.py

---

2048

项目需求

• 直接在控制台使用命令行运行
• 运行之后出现2048小游戏

项目练习

• Turtle
• 二维列表

项目参考代码

见上方代码。

测试运行

将代码保存为game.py，然后在控制台运行：

python game.py
