文本编辑器的python代码

以下是一个简单的Python文本编辑器的代码示例：

import tkinter as tk
from tkinter import filedialog

class TextEditor:
    def __init__(self, master):
        self.master = master
        self.master.title("Text Editor")
        self.text = tk.Text(self.master)
        self.text.pack(fill=tk.BOTH, expand=True)
        self.menu_bar = tk.Menu(self.master)
        self.file_menu = tk.Menu(self.menu_bar, tearoff=0)
        self.file_menu.add_command(label="New", command=self.new_file)
        self.file_menu.add_command(label="Open", command=self.open_file)
        self.file_menu.add_command(label="Save", command=self.save_file)
        self.file_menu.add_separator()
        self.file_menu.add_command(label="Exit", command=self.master.quit)
        self.menu_bar.add_cascade(label="File", menu=self.file_menu)
        self.edit_menu = tk.Menu(self.menu_bar, tearoff=0)
        self.edit_menu.add_command(label="Cut", command=self.cut)
        self.edit_menu.add_command(label="Copy", command=self.copy)
        self.edit_menu.add_command(label="Paste", command=self.paste)
        self.menu_bar.add_cascade(label="Edit", menu=self.edit_menu)
        self.master.config(menu=self.menu_bar)
        
    def new_file(self):
        self.text.delete(1.0, tk.END)
        
    def open_file(self):
        file_path = filedialog.askopenfilename()
        if file_path:
            with open(file_path, "r") as f:
                file_contents = f.read()
            self.text.delete(1.0, tk.END)
            self.text.insert(tk.END, file_contents)
        
    def save_file(self):
        file_path = filedialog.asksaveasfilename()
        if file_path:
            with open(file_path, "w") as f:
                f.write(self.text.get(1.0, tk.END))
                
    def cut(self):
        self.text.event_generate("<<Cut>>")
        
    def copy(self):
        self.text.event_generate("<<Copy>>")
        
    def paste(self):
        self.text.event_generate("<<Paste>>")
        
root = tk.Tk()
text_editor = TextEditor(root)
root.mainloop()

该代码使用了Tkinter模块来构建GUI，并实现了基本的文本编辑功能。它包括打开、保存、复制、剪切和粘贴文件等功能。如果您需要更高级的功能，您可以在此基础上进行扩展。
