如何隐藏基于单选按钮选择的tkinter小部件？

Question

我正在尝试使用tkinter编写Python 3代码，以根据输入的数据生成体积计算。

当前，我的代码有效，但是我想做的是，当通过单选按钮选择矩形棱柱时，球形小部件消失了，反之亦然，所以只显示了相关的项目。

我找到了一些想法，但是在当前设置中很难实现它们。如果有人可以提供帮助，我将非常感谢。

代码：

要实现此目的，您可以将长方体和球体所需的小部件放在不同的框架中，并将命令参数添加到单选按钮中，单选按钮被选中时将显示相应的框架，而grid_forget将显示另一个框架。这是代码。 （请注意，我对此 volumes 模块一无所知，因此您可以相应地对其进行更改）

from tkinter import *
from tkinter import messagebox

def calculate(): #assigns vars, calls volumes module
    x = option.get()
    if x == 1:
        heightx = heighttxt.get()
        widthx = widthtxt.get()
        lengthx = lengthtxt.get()

        height = float(heightx)
        width = float(widthx)
        length = float(lengthx)

        volume = length*width*height

        messagebox.showinfo('You selected Rectangular Prism', volume) #displays calculation result

    if x == 2:
        radx = radtxt.get()
        radius = float(radx)
        volume = 4/3*3.14*radius**3
        messagebox.showinfo('You selected Sphere', volume) #displays calculation result

def recprism():
    sphere_frame.grid_forget()
    rec_frame.grid(row=1, column=0)

def sphere():
    rec_frame.grid_forget()
    sphere_frame.grid(row=1, column=0)

window = Tk() #creates window ident

window.title("Volume Calculator")
window.geometry('450x300')

option = IntVar()

Radiobutton(window, text="Rectangular Prism", variable=option, value=1, command=recprism).grid(column=0, row=0)
Radiobutton(window, text="Sphere", variable=option, value=2, command=sphere).grid(column=1, row=0)

rec_frame = Frame(window)
sphere_frame = Frame(window)

heightlbl = Label(rec_frame, text="Enter the height: ", padx=5, pady=5) #creates ident labels
widthlbl = Label(rec_frame, text="Enter the width: ", padx=5, pady=5)
lengthlbl = Label(rec_frame, text="Enter the length: ", padx=5, pady=5)

radlbl = Label(sphere_frame, text ="Enter the radius of a sphere: ", padx=5, pady=5)

heighttxt = Entry(rec_frame, width=10) #creates entry boxes
widthtxt = Entry(rec_frame, width=10)
lengthtxt = Entry(rec_frame, width=10)

radtxt = Entry(sphere_frame, width=10)

calcbtn = Button(window, text="Calculate the volume", command=calculate, padx=5, pady=5) #hey it's a button that calls the calculate function!
quitbtn = Button(window, text="Quit", command=window.destroy) #quit button does what it says on the tin


heightlbl.grid(column=0, row=0) #assigns grid positions (preferred to pack for precise layout)
widthlbl.grid(column=0, row=1)
lengthlbl.grid(column=0, row=2)
radlbl.grid(column=0, row=0)
heighttxt.grid(column=1, row=0)
widthtxt.grid(column=1, row=1)
lengthtxt.grid(column=1, row=2)
radtxt.grid(column=1, row=0)

calcbtn.grid(column=1, row=1)
quitbtn.grid(column=1, row=2)

window.mainloop()
