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()
