如何在python中显示同一类的不同函数的文本框中的文本

import tkinter as tk

class MyClass:
    def __init__(self):
        self.root = tk.Tk()
        self.textbox = tk.Text(self.root)
        self.button1 = tk.Button(self.root, text="Function 1", command=self.show_text1)
        self.button2 = tk.Button(self.root, text="Function 2", command=self.show_text2)
        self.textbox.pack()
        self.button1.pack()
        self.button2.pack()

    def show_text1(self):
        self.textbox.delete("1.0", tk.END)  # 清空文本框
        text = "这是函数1的文本"
        self.textbox.insert(tk.END, text)

    def show_text2(self):
        self.textbox.delete("1.0", tk.END)  # 清空文本框
        text = "这是函数2的文本"
        self.textbox.insert(tk.END, text)

    def run(self):
        self.root.mainloop()

my_obj = MyClass()
my_obj.run()
