使用tkinter和类创建多个不同颜色的形状

import tkinter as tk

class ShapeCanvas(tk.Canvas):
    def __init__(self, master, color):
        super().__init__(master, width=200, height=200)
        self.color = color

    def draw_rectangle(self):
        self.create_rectangle(50, 50, 150, 150, fill=self.color)

    def draw_oval(self):
        self.create_oval(50, 50, 150, 150, fill=self.color)

if __name__ == "__main__":
    root = tk.Tk()

    canvas1 = ShapeCanvas(root, "red")
    canvas1.draw_rectangle()
    canvas1.pack(side=tk.LEFT)

    canvas2 = ShapeCanvas(root, "green")
    canvas2.draw_oval()
    canvas2.pack(side=tk.LEFT)

    root.mainloop()
