python名片管理教程_使用python实现名片管理系统

python实现名片管理系统(界面+数据库)

开发一个简单的信息管理系统(类似于前面的名片管理系统)，要求：

1.用结构化方法或面向对象开发方法开发系统

2.有图形用户界面

3.用数据库存储数据

4.用python语言实现系统

部分功能如下图

进入时的界面

显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(修改名片和删除名片)

具体代码如下

import sys

from tkinter import *

from tkinter.messagebox import *

from tkinter import ttk

import sqlite3

con = sqlite3.connect(r"D:\Python练习\作业\12月6日python\card.db")

#con.execute("create table card(name primary key ,phone,QQ,email)")

#新增名片

def add():

add = Tk()

add.geometry('260x140+350+200')

add.minsize(260, 140)

add.maxsize(260, 140)

add.title("新建名片")

lf = LabelFrame(add,text="请 输 入 ：",labelanchor=N)

lf.pack()

Label(lf, text="姓 名：").grid(row=0,column=0)

Label(lf, text="电 话：").grid(row=1,column=0)

Label(lf, text="Q Q：").grid(row=2, column=0)

Label(lf, text="Email：").grid(row=3, column=0)

name = Entry(lf)

name.grid(row=0,column=1,columnspan=2)

phone.grid(row=1,column=1,columnspan=2)
