python實戰案例：基于Pygame的飛機大戰游戲

飛機大戰大家都熟悉不過了，相信每個人都有這么一段美好的回憶，作為程式員的我們是不是可以用代碼來回憶一下我們失去的青春，python語言博大精深，它目前來說已經很火熱了，在學好python的同時還要學會用python，可以使用它來開發一些專案最好不過了，
該游戲在開發之前用到Pygame庫，大家一定要記著安裝哦！
也可以先通過下列命令查看你是否安裝了第三方庫Pygame，

pip list

可以看得到我已經安裝成功了，如果沒有安裝，那就請參考文獻python在是那種不同軟體方式安裝第三方庫請點擊這里

先看看游戲進行時的場面：

展示一下python源代碼：

看代碼感覺很簡單，但是要切實際的運行出來是非常難得，本游戲用到的游戲場景照片均參考自python專案案例開發到入門，大家如果感興趣可以自己買了多看看哦，
