python语言实现贪吃蛇游戏

本文实例为大家分享了python实现贪吃蛇游戏的具体代码,供大家参考,具体内容如下

新手自学python(简易贪吃蛇代码)
环境python3.7

刚刚大学毕业进入工作岗位,发现同事基本都会写py脚本,于是自学了一下,并写了一个简单的贪吃蛇代码,我觉得写的还是比较容易看懂,适合新手接触python。

# 第1步,实例化object,建立窗口window
window = tk.Tk() 
# 第2步,给窗口的可视化起名字
window.title('Greedy snake')
# 第3步,设定窗口的大小(长 * 宽)
# window.geometry('1004x504')  # 这里的乘是小x

# 第5步,创建一个主frame,长在主window窗口上
frame = tk.Frame(window, bg = 'blue', bd = 2, relief = tk.FLAT)
frame.pack(side = 'left')
#当前框架被选中,意思是键盘触发,只对这个框架有效
frame.focus_set()
