10 gobang

Requirements

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

What will we practice in this project?

  • turtle draw
  • mouse click event handle
  • 2d array
  • list
  • exception handle
  • function

A reference code

Run the demo

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

python gobang.py

1分钟数学运算

项目需求

  • 直接在控制台使用命令行运行
  • 运行之后出现五子棋小游戏

项目练习

  • turtle工具包
  • 自定义函数
  • 二维列表
  • 鼠标事件

项目参考代码

# 导入turtle工具包
from turtle import *

# 输赢
win = False

# 最快速度
speed(0)
# 背景颜色
bgcolor("lightgreen")
# 颜色变量，默认是黑色
yanse="black"
# 格子大小
gz=40

judge = Turtle()
judge.up()
judge.goto(-460, 330)
judge.write("谁下", font=("Kai", 40, "bold"))
judge.color(yanse)
judge.goto(-420, 300)
judge.dot(30)

# 画19条横线
for i in range(19):
    up()
    goto(-gz*9, gz*(9-i))
    down()
    fd(gz*18)
    bk(gz*18)
