我是 python 新手，正在尝试将这些文件夹中的文件夹名称和文本文件添加到数据库中。问题是我不知道如何将“textfiles”和“opendirectory”添加到数据库中。请查看此代码并帮助我。谢谢

#!/usr/bin/python

from easygui import *
import sys, glob, os, sqlite3


msgbox("Please choose your folder ","Welcome to MTT", ok_button ="Choose")

opendirectory = diropenbox("Welcome", "MTT",None)


con = sqlite3.connect('test.db')
cur = con.cursor()
cur.execute('DROP TABLE IF EXISTS folder')
cur.execute('DROP TABLE IF EXISTS file')
cur.execute('CREATE TABLE folder( folderid INTEGER PRIMARY KEY, foldername   VARCHAR(120))')
cur.execute('CREATE TABLE file( fileid INTEGER PRIMARY KEY, folderid INTEGER, dataname VARCHAR(120), FOREIGN KEY(folderid) REFERENCES foldername(folderid))')
con.commit()


def main():

    for dirpath,dirnames,filenames in os.walk(opendirectory):

        for textfiles in filenames:

            print textfiles
            print opendirectory
            cur.execute ('INSERT INTO folder (folderid, foldername) VALUES (null,opendirector)')
            cur.execute('INSERT INTO file(fileid, dataname) VALUES(null,textfiles)')
            cur.execute('SELECT * FROM folder')
            print cur.fetchall()


main()

print 'success'

假设您想将所有文件名添加到数据库中（不考虑它们在内部的相对路径opendirectory），这是一种更正查询的方法。

cur.execute ("INSERT INTO folder (foldername) VALUES (?);", (opendirectory))
cur.execute("INSERT INTO file (dataname) VALUES(?);", (textfiles))

注意：这不足以在文件和文件之间建立数据库中的逻辑链接opendirectory。

现在，假设您想在数据库中存储文件的父文件夹的路径以及文件parent_folder名：只需在表中添加一列file，并使用这样的插入查询（我更改了变量名以使其更容易理解）：

for dirpath, dirsInDirpath, filesInDirPath in os.walk(opendirectory):
    for myfile in filesInDirPath:   
        cur.execute("INSERT INTO file (dataname, parent_folder) VALUES(?, ?);", (myfile, dirpath))
