开发一个GUI界面，对两个十进制数字执行按位AND，OR，NOT，XOR运算，并使用python进行解释

Question

我想让python程序看起来像this 所以我做了类似的代码看：

from Tkinter import *
import Tkinter
import tkMessageBox
top=Tkinter.Tk()
def and1(a,b):
    print int(a and b)
def or1(a,b):
    print int(a or b)
def not1(a):
    print int(not a)
def xor1(a,b):
    print int((a and not b) or (not a and b))
def exit1(top):
    top.destroy()
def exit2(top):
    top.destroy()
def expl():
    top=Tkinter.Tk()
    l1=Label(top,text="Number 1").grid(row=0,column=0)
    e1=Entry(top,bd=5)
    e1.grid(row=0,column=1)
    e3=Entry(top,bd=5)
    l3=Label(top,text="Binary Number 1").grid(row=0,column=2)
    e3.grid(row=0,column=3)
    l2=Label(top,text="Number 2").grid(row=1,column=0)
    e2=Entry(top,bd=5)
    e2.grid(row=1,column=1)
    l4=Label(top,text="Binary Number 2").grid(row=1,column=2)
    e4=Entry(top,bd=5)
    e4.grid(row=1,column=3)
    l5=Label(top,text="t.f.p.r.s").grid(row=2,column=2) #says text from previous radiobutton selection
    e5=Entry(top,bd=5)
    e5.grid(row=2,column=3)
    l6=Label(top,text="Decimal Result").grid(row=3,column=1)
    e6=Entry(top,bd=5)
    e6.grid(row=3,column=2)
    b1=Tkinter.Button(top,bd=5,text="Exit",command=lambda top=top:exit2(top)).grid(row=4,column=0)
    top.mainloop()
L1=Label(top,text="Number 1").grid(row=0,column=0)
E1=Entry(top,bd=5)
E1.grid(row=0,column=1)
L2=Label(top,text="Number 2").grid(row=0,column=2)
E2=Entry(top,bd=5)
E2.grid(row=0,column=3)
var=IntVar()
R1=Radiobutton(top,text="AND",variable=var,value=1,command="and1")
R1.grid(row=1,column=0)
R2=Radiobutton(top,text="OR",variable=var,value=2,command="or1")
R2.grid(row=1,column=1)
R3=Radiobutton(top,text="NOT",variable=var,value=3,command="not1")
R3.grid(row=2,column=0)
R4=Radiobutton(top,text="XOR",variable=var,value=4,command="xor1")
R4.grid(row=2,column=1)
label=Label(top)
label.grid()
B1=Tkinter.Button(top,text="Result is:",command="result",bd=5)
B1.grid(row=3,column=0)
B2=Tkinter.Button(top,text="Explanation",command=expl,bd=5)
B2.grid(row=3,column=1)
B3=Tkinter.Button(top,bd=5,text="Exit",command=lambda top=top:exit1(top)).grid(row=3,column=2)
L3=Label(top,text="Result is:").grid(row=4,column=0)
E3=Entry(top,bd=5)
E3.grid(row=4,column=1)
top.mainloop()

现在修改了。我希望用户应该在第一帧中输入值并相应地得到结果，同样在解释点击时，其他帧打开并仅使用之前的值进行解释。

我不知道该说些什么。我不想为你彻底解决问题，但我希望更好地理解Python的Tkinker。阅读课程，将来会有所帮助。
