请编写python代码，创建gui，实现文件读取和写入以及删除

### 回答1：

# 参考代码
from tkinter import *root = Tk()
root.geometry('500x500')
root.title('文件读写删除GUI')def read_file():
passdef write_file():
passdef delete_file():
passlabel_1 = Label(root, text='请选择操作：', font=('Arial', 12))
label_1.place(x=20, y=20)button_1 = Button(root, text='读取文件', font=('Arial', 12), command=read_file)
button_1.place(x=20, y=50)button_2 = Button(root, text='写入文件', font=('Arial', 12), command=write_file)
button_2.place(x=130, y=50)button_3 = Button(root, text='删除文件', font=('Arial', 12), command=delete_file)
button_3.place(x=240, y=50)root.mainloop()

import tkinter as tk
from tkinter import filedialog

def read_file():
filename = filedialog.askopenfilename()
if filename:
with open(filename, 'r') as file:
text_area.delete('1.0', tk.END)
text_area.insert(tk.END, file.read())

def write_file():
filename = filedialog.asksaveasfilename(defaultextension=".txt")
if filename:
with open(filename, 'w') as file:
file.write(text_area.get('1.0', tk.END))

def delete_file():
filename = filedialog.askopenfilename()
if filename:
try:
os.remove(filename)
text_area.delete('1.0', tk.END)
tk.messagebox.showinfo("删除成功", "文件删除成功！")
except:
tk.messagebox.showerror("删除失败", "文件删除失败！")

window = tk.Tk()
window.title("文件操作")
window.geometry("300x200")

btn_read = tk.Button(window, text="读取文件", command=read_file)
btn_read.pack(pady=10)

btn_write = tk.Button(window, text="写入文件", command=write_file)
btn_write.pack(pady=10)

btn_delete = tk.Button(window, text="删除文件", command=delete_file)
btn_delete.pack(pady=10)

text_area = tk.Text(window, height=8)
text_area.pack()

window.mainloop()

要实现文件的读取、写入和删除功能，你可以使用Python的tkinter库来创建GUI界面，并且使用文件操作函数来实现对文件的读写和删除操作。

首先，你需要导入tkinter和os模块：

import tkinter as tk
import os

然后，创建一个GUI窗口：

window = tk.Tk()
window.title("文件操作")

接下来，创建三个函数来实现文件的读取、写入和删除操作：

def read_file():
    file_name = file_entry.get()
    try:
        with open(file_name, "r") as f:
            file_contents.delete(1.0, tk.END)
            file_contents.insert(tk.END, f.read())
    except FileNotFoundError:
        file_contents.delete(1.0, tk.END)
        file_contents.insert(tk.END, "文件不存在！")

def write_file():
    file_name = file_entry.get()
    file_content = file_contents.get(1.0, tk.END)
    with open(file_name, "w") as f:
        f.write(file_content)
    file_contents.delete(1.0, tk.END)
    file_contents.insert(tk.END, "文件写入成功！")

def delete_file():
    file_name = file_entry.get()
    try:
        os.remove(file_name)
        file_contents.delete(1.0, tk.END)
        file_contents.insert(tk.END, "文件删除成功！")
    except FileNotFoundError:
        file_contents.delete(1.0, tk.END)
        file_contents.insert(tk.END, "文件不存在！")

接下来，创建界面的组件：

file_label = tk.Label(window, text="文件名：")
file_label.pack()

file_entry = tk.Entry(window)
file_entry.pack()

read_button = tk.Button(window, text="读取文件", command=read_file)
read_button.pack()

write_button = tk.Button(window, text="写入文件", command=write_file)
write_button.pack()

delete_button = tk.Button(window, text="删除文件", command=delete_file)
delete_button.pack()

file_contents = tk.Text(window)
file_contents.pack()

最后，启动GUI界面的主循环：

window.mainloop()

这样，你就创建了一个能够实现文件读取、写入和删除的GUI程序。你可以在文本框中输入文件名，然后点击相应的按钮来执行操作。
