如何将 Turtle 与 tkinter 结合使用

Question

So I've got tkinter code that when ran, opens up a new window with a square root calculator, when I try to get turtle in the same window as the square root calculator, 2 windows pop up

import tkinter as tk
from turtle import Turtle, Screen
root = tk.Tk()

canvas1 = tk.Canvas(root, width=400, height=300, relief='raised')
canvas1.pack()

label1 = tk.Label(root, text='Square root calculator')
label1.config(font=('helvetica', 14))
canvas1.create_window(200, 25, window=label1)

label2 = tk.Label(root, text='Enter number:')
label2.config(font=('helvetica', 10))
canvas1.create_window(200, 100, window=label2)

entry1 = tk.Entry(root)
canvas1.create_window(200, 140, window=entry1)



def sqr():
    x1 = entry1.get()

    label3 = tk.Label(root, text='The Square root of ' + x1 + ' is:', font=('helvetica', 10))
    canvas1.create_window(200, 210, window=label3)

    label4 = tk.Label(root, text=float(x1) ** 0.5, font=('helvetica', 10, 'bold'))
    canvas1.create_window(200, 230, window=label4)


button1 = tk.Button(text='Calculate square root', command=sqr, bg='brown', fg='white',
                    font=('helvetica', 9, 'bold'))
canvas1.create_window(200, 180, window=button1)
pamest = tk.Button(root, text="Quit", command=root.destroy)
pamest.pack(pady=20)

screen = Screen()
screen.setup(500,350)
screen.screensize(600,600)
turtle = Turtle()
turtle.up()


root.mainloop()

Start with the turtle documentation sections that explain the standalone vs. embedded use of turtle. You're trying to use turtle in an embedded situation but are using the standalone API. We can implement what you're trying to do as follows:

import tkinter as tk
from turtle import RawTurtle, TurtleScreen

def sqr():
    x1 = entry1.get()

    label3 = tk.Label(root, text='The Square root of ' + x1 + ' is:', font=('helvetica', 10))
    canvas1.create_window(200, 210, window=label3)

    label4 = tk.Label(root, text=float(x1) ** 0.5, font=('helvetica', 10, 'bold'))
    canvas1.create_window(200, 230, window=label4)

root = tk.Tk()

canvas1 = tk.Canvas(root, width=400, height=600, relief='raised')
canvas1.pack()

tk.Button(root, text="Quit", command=root.destroy).pack(pady=20)

label1 = tk.Label(root, text='Square root calculator', font=('helvetica', 14))
canvas1.create_window(200, 25, window=label1)

label2 = tk.Label(root, text='Enter number:', font=('helvetica', 10))
canvas1.create_window(200, 100, window=label2)

entry1 = tk.Entry(root)
canvas1.create_window(200, 140, window=entry1)

button1 = tk.Button(text='Calculate square root', command=sqr, font=('helvetica', 9, 'bold'))
canvas1.create_window(200, 180, window=button1)

canvas2 = tk.Canvas(canvas1, width=400, height=300)
canvas1.create_window(203, 450, window=canvas2)

screen = TurtleScreen(canvas2)
screen.bgcolor('pink')

turtle = RawTurtle(screen)
turtle.circle(50)

screen.mainloop()
