python實(shí)現(xiàn)名片管理系統(tǒng)（界面+數(shù)據(jù)庫(kù)）

開(kāi)發(fā)一個(gè)簡(jiǎn)單的信息管理系統(tǒng)（類(lèi)似于前面的名片管理系統(tǒng)），要求：
1.用結(jié)構(gòu)化方法或面向?qū)ο箝_(kāi)發(fā)方法開(kāi)發(fā)系統(tǒng)
2.有圖形用戶界面
3.用數(shù)據(jù)庫(kù)存儲(chǔ)數(shù)據(jù)
4.用python語(yǔ)言實(shí)現(xiàn)系統(tǒng)

部分功能如下圖

進(jìn)入時(shí)的界面
顯示所有名片后的界面
新建名片功能

新建成功

查找名片里包含（修改名片和刪除名片）

具體代碼如下
