Question

我对编程和python相对较新。我正在为健身房构建这个应用程序，使用tkinter输入客户详细信息，我把它全部运行但我需要一种方法将客户的电话号码从sqlite3数据库中提取到txt文件。

这是后端脚本

import sqlite3

class database:
    def __init__(self,db):
        self.conn=sqlite3.connect(db)
        self.cur=self.conn.cursor()
        self.cur.execute("CREATE TABLE IF NOT EXISTS Customers (id INTEGER PRIMARY KEY, name text, Phone integer, gender text, DoB date )")
        self.conn.commit()

    def add(self,name,phone,gender,DoB):
        self.cur.execute("INSERT INTO Customers VALUES (NULL,?,?,?,?)",(name,phone,gender,DoB))
        self.conn.commit()

    def search(self,name="",phone="",DoB=""):
        self.cur.execute("SELECT * FROM Customers WHERE name=? OR phone=? OR DoB=?",(name,phone,DoB))
        rows=self.cur.fetchall()
        return rows

    def view(self):
        self.cur.execute("SELECT * FROM Customers")
        rows=self.cur.fetchall()
        return rows

    def delete(self,id):
        self.cur.execute("DELETE FROM Customers WHERE id=?",(id,))
        self.conn.commit()

    def edit(self,id,name,phone,gender,DoB):
        self.cur.execute("UPDATE Customers SET name=?,phone=?,gender=?,DoB=? WHERE id=?",(name,phone,gender,DoB,id))
        self.conn.commit()

    def __del__(self):
        self.conn.close()

那么如何将输入到手机条目小部件中的每个新电话号码保存到txt文件，以便我只能访问电话号码

Answer 1

你可以这样做：

def write_to_text_file(self):
    self.cur.execute("SELECT phone FROM Customers")
    rows = self.cur.fetchall()
    with open('phone_numbers','ab') as fou:
        for row in rows:
            fou.write(row[0])
    return fou

每次插入记录时都要更新：

def add(self,name,phone,gender,DoB):
    self.cur.execute("INSERT INTO Customers VALUES (NULL,?,?,?,?)",(name,phone,gender,DoB))
    self.conn.commit()
    self.write_to_text_file(self)
