依照计算机自带的画图软件的功能编写一个有可视化界面的python画图软件

好的，我可以为你提供一个简单的Python Tkinter GUI画图工具。下面是代码：

import tkinter as tk
from tkinter import ttk
from tkinter import colorchooser
from tkinter import messagebox
from tkinter import filedialog


class Paint:
    def __init__(self, root):
        self.root = root
        self.root.title("Paint")
        self.root.geometry("800x600")

        self.pen_color = "black"
        self.bg_color = "white"
        self.pen_width = 3

        self.create_widgets()
        self.create_menu()

    def create_widgets(self):
        self.canvas = tk.Canvas(self.root, bg=self.bg_color, width=800, height=500)
        self.canvas.pack(fill=tk.BOTH, expand=True)

        self.pen_color_button = tk.Button(self.root, text="Pen Color", command=self.choose_pen_color)
        self.pen_color_button.pack(side=tk.LEFT, padx=5)

        self.erase_button = tk.Button(self.root, text="Erase", command=self.erase)
        self.erase_button.pack(side=tk.LEFT, padx=5)

        self.pen_width_label = tk.Label(self.root, text="Pen Width:")
        self.pen_width_label.pack(side=tk.LEFT, padx=5)

        self.pen_width_entry = ttk.Combobox(self.root, values=["1", "2", "3", "4", "5"])
        self.pen_width_entry.current(2)
        self.pen_width_entry.pack(side=tk.LEFT)

        self.clear_button = tk.Button(self.root, text="Clear", command=self.clear)
        self.clear_button.pack(side=tk.LEFT, padx=5)

        self.save_button = tk.Button(self.root, text="Save", command=self.save)
        self.save_button.pack(side=tk.LEFT, padx=5)

    def create_menu(self):
        self.menu_bar = tk.Menu(self.root)
        self.file_menu = tk.Menu(self.menu_bar, tearoff=0)
        self.file_menu.add_command(label="New", command=self.clear)
        self.file_menu.add_command(label="Open", command=self.open_file)
        self.file_menu.add_command(label="Save", command=self.save)
        self.file_menu.add_separator()
        self.file_menu.add_command(label="Exit", command=self.root.quit)
        self.menu_bar.add_cascade(label="File", menu=self.file_menu)

        self.root.config(menu=self.menu_bar)

    def choose_pen_color(self):
        color = colorchooser.askcolor()
        if color:
            self.pen_color = color[1]

    def erase(self):
        self.pen_color = self.bg_color

    def clear(self):
        self.canvas.delete("all")

    def save(self):
        file_path = filedialog.asksaveasfilename(defaultextension=".png")
        if file_path:
            self.canvas.postscript(file=file_path + ".eps")
            messagebox.showinfo("Save", "Image saved successfully!")

    def open_file(self):
        file_path = filedialog.askopenfilename(filetypes=[("EPS Files", "*.eps")])
        if file_path:
            self.clear()
            self.canvas.create_image(400, 250, image=tk.PhotoImage(file=file_path))

    def draw(self, event):
        x1, y1 = (event.x - self.pen_width), (event.y - self.pen_width)
        x2, y2 = (event.x + self.pen_width), (event.y + self.pen_width)
        self.canvas.create_oval(x1, y1, x2, y2, fill=self.pen_color, outline=self.pen_color)

    def start_draw(self, event):
        self.canvas.bind("<B1-Motion>", self.draw)

    def stop_draw(self, event):
        self.canvas.unbind("<B1-Motion>")

    def run(self):
        self.canvas.bind("<Button-1>", self.start_draw)
        self.canvas.bind("<ButtonRelease-1>", self.stop_draw)
        self.root.mainloop()


if __name__ == '__main__':
    paint = Paint(tk.Tk())
    paint.run()

该程序实现了以下功能：

1. 画布
2. 选择画笔颜色
3. 橡皮擦
4. 选择画笔宽度
5. 清空画布
6. 保存画布
7. 打开画布
8. 实现了菜单栏和快捷键

你可以在本地运行这个程序并进行测试。
