python3.6.0-32 sqlite tkdnd tkinterdnd2 拖拽 快捷方式管理

快捷方式管理（pyqt5升级版，不在对这篇更新）https://blog.51cto.com/ikezcn/2166426
连接sqlite3
python软件:https://www.python.org/ftp/python/3.6.0/python-3.6.0.exe

pytho自带sqlite3,所以只需要import
简单例子:

import sqlite3
db = sqlite3.connect("./db") #在调用connect函数并指定库名称,如果不存在会按指定库名称自动创建.
cu = db.cursor()#游标
#cu.execute("create table lj(id integer primary key,lj text not NULL)") #执行sql语句
#cu.execute("insert into lj(lj) values('c:\python27')")
db.commit()#事务提交
cu.execute("select * from lj;")#查询
print cu.fetchall()#打印查询结果,结果是{1 {c:\python27}}
cu.close()#关闭游标
db.close()#关闭数据库连接

官方超详细说明:https://docs.python.org/3.7/library/sqlite3.html

pywin32这个库主要包含win32api和win32con
安装:pip install pywin32
简单例子:

import win32api
import win32con
win32api.MessageBox(win32con.NULL, '显示内容', '标题', win32con.MB_OK)
win32api.ShellExecute(0,'open',r'D:.txt','','',1)#不会像os.system弹出黑框

windnd对 windows 桌面图标拖拽加载路径
安装:pip install windnd
简单例子:

from tkinter import *
import windnd

for idx,i in enumerate(ls):
    print(idx,i)

tk = Tk()
windnd.hook_dropfiles(tk,func = my_func
tk.mainloop() 

ps:遇到问题,在使用滚动条的时候会发生错误,没有继续调试下去,换了tkdnd

tkdnd2.8 tkinterDnD2
软件:
tkdnd2.8 https://sourceforge.net/projects/tkdnd/
TkinterDnD2 http://sourceforge.net/projects/tkinterdnd/files/

安装:
将tkdnd2.8文件夹复制到c:\Python36-32\tcl\
将TkinterDnD2文件夹复制到C:\Python36-32\Lib\ (下载的是TkinterDnD2-0.2文件夹要复制的是里面的那个)

简单例子:
直接使用TkinterDnD2-0.2文件夹下的demo

故事的开头:公司妹子突然发彪说快捷方式全部消失.不高兴找原因了,然后找的软件被嫌弃太复杂,所以…自己写了一个功能简单的软件
喜欢的拿去随便用不过记得点赞.我会不定期的更新,需要增加功能的朋友请留言
