我知道我能做到。..

import tkinter as tk

root=tk.Tk()
root.geometry("800x600")
#Note if '=' is used, i.e. root.geometry=("800x600")
# then tkinter root(window) does NOT display full area

canv1=tk.Canvas(bg="green", height=150, width=200)
canv1.place(x=20,y=10)

root.mainloop()

理想情况下，我想做很多画布，当我学习类时，我想到这可以通过使用类来完成，这样我就可以更容易，更快速地示例化用户定义的画布。..canv2 = InstantCanvas（橙子，100，250）
我觉得这似乎是合理的：

import tkinter as tk

root=tk.Tk()
root.geometry("400x300")

class InstantCanvas():
    def __init__(self, background, height, width):
        self = self.tk.Canvas(background, height, width)
        # trying to achieve "my_user_canvas.

#Note if '=' is used, i.e. root.geometry=("800x600")
# then tkinter root(window) does NOT display full area

# Reference canvas, manually made
canv1=tk.Canvas(bg="green", height=150, width=200)
canv1.place(x=20,y=10)

canv2 = InstantCanvas("orange", 100, 250)
canv2.place(x=40,y=50)

root.mainloop()

但我得到一个错误。..AttributeError：“InstantCanvas”对象没有属性“tk”
所以我必须把import tkinter as tk放在类init函数中？看起来很奇怪和多余，但我还是试了。..

import tkinter as tk

root=tk.Tk()
root.geometry("400x300")

class InstantCanvas():
    import tkinter as tk
    def __init__(self, background, height, width):
        self = self.tk.Canvas(background, height, width)
        # trying to achieve "my_user_canvas.

#Note if '=' is used, i.e. root.geometry=("800x600")
# then tkinter root(window) does NOT display full area

# Reference canvas, manually made
canv1=tk.Canvas(bg="green", height=150, width=200)
canv1.place(x=20,y=10)

canv2 = InstantCanvas("orange", 100, 250)
canv2.place(x=40,y=50)

root.mainloop()

现在我得到了太多的参数错误，特别是Canvas。init（）接受1到3个位置参数，但有4个被给出了，但我认为init有点忽略了 self 作为一个“硬”参数，但如果我把 self 去掉，那么我的init函数将无法“连接”到示例化的对象。那怎么做
关于为什么它不起作用以及如何使它起作用的反馈将不胜感激。Tq.
