如何从用户获取输入，并在tkinter中将输入作为python代码(Sql)执行？

import tkinter as tk
import sqlite3

window = tk.Tk()
window.title("SQL执行器")

sql_entry = tk.Entry(window, width=50)
sql_entry.pack()

def execute_sql():
    sql = sql_entry.get()  # 获取用户输入的SQL代码
    conn = sqlite3.connect("database.db")  # 连接数据库
    cursor = conn.cursor()
    cursor.execute(sql)  # 执行SQL代码
    result = cursor.fetchall()  # 获取执行结果
    conn.commit()
    conn.close()
    # 在界面上显示执行结果
    result_text.delete(1.0, tk.END)
    result_text.insert(tk.END, str(result))

execute_button = tk.Button(window, text="执行SQL", command=execute_sql)
execute_button.pack()

result_text = tk.Text(window, height=10, width=50)
result_text.pack()

window.mainloop()
