本文例項為大家分享了python實現貪吃蛇遊戲的具體程式碼，供大家參考，具體內容如下

新手自學python（簡易貪吃蛇程式碼）
環境python3.7

剛剛大學畢業進入工作崗位，發現同事基本都會寫py指令碼，於是自學了一下，並寫了一個簡單的貪吃蛇程式碼，我覺得寫的還是比較容易看懂，適合新手接觸python。

# 第1步，例項化object，建立視窗window

# 第2步，給視窗的視覺化起名字
window.title('Greedy snake')
# 第3步，設定視窗的大小(長 * 寬)
# window.geometry('1004x504')  # 這裡的乘是小x

# 第5步，建立一個主frame，長在主window視窗上
