Question

所以我创建了一个程序，然后单击第一个单选按钮，然后单击显示“获取总成本”的按钮，当窗口打开时，它并没有给我正确的价值。

import tkinter as tk
#make a new window
window10 = tk.Tk()
#lable what the page is
amgpage = tk.Label(window10, text="Mercedes Benz AMG Maintenance Calculator")
amgpage.pack(anchor='n')

#ask the user how many tires are needed
amgpage = tk.Label(window10, text="How many new tires do you need?")
amgpage.pack(anchor='w')

gr1=tk.IntVar()

def amgtires():
    x=227.92
    tiresa=(gr1.get())

    if (tiresa == 1):
        c=x
    elif(tiresa == 2):
        c=x+x
    elif(tiresa == 3):
        b=x+x+x
    elif(tiresa == 4):
        d=x+x+x+x
    elif(tiresa == 5):
        e=0
    return tiresa

def amgtotal():
#open a new page
    window17 = tk.Tk()
    a = amgtires()

    #total cost for tires
    amgpage = tk.Label(window17, text="Tire Cost: $"+ str(a))
    amgpage.pack(anchor='w')

    #size for window
    window17.geometry("400x400")

    #window title   
    window17.title("Mercedes Benz AMG Maintenance Total")

    #end of window 17   
    window17.mainloop()


#radio button on how many tire are needed
tire = tk.Radiobutton(window10, text="1",value=1,variable=gr1,command=amgtires).pack(anchor='w' )
tire = tk.Radiobutton(window10, text="2",value=2,variable=gr1,command=amgtires).pack(anchor='w' )
tire = tk.Radiobutton(window10, text="3",value=3,variable=gr1,command=amgtires).pack(anchor='w' )
tire = tk.Radiobutton(window10, text="4",value=4,variable=gr1,command=amgtires).pack(anchor='w' )
tire = tk.Radiobutton(window10, text="None",value=5,variable=gr1,command=amgtires).pack(anchor='w' )

#Get the total cost for maintenace
amgpage = tk.Button(window10,text= "Get total cost", command = amgtotal,fg = 'Green')
amgpage.pack(anchor='w')



#size for window size
window10.geometry("700x400")

#window title       
window10.title("Mercedes Benz AMG Maintenance Calculator")

#end of window10 loop
window10.mainloop()

因此，当我单击一个轮胎时，我只希望227.92和2个轮胎获得两个轮胎等的值。

Answer 1

有很多不必要的代码块。我已对其进行了更正，但是它可以变得更好。

您不需要两个mainloop，一个就足够显示所需的Toplevel或Tk窗口。所以我删除了window17.mainloop()。
还使用Toplevel窗口代替另一个主窗口Tk。 Toplevel exists.
有很多方法可以获取所需的值，我只是使用了最简单的方法来删除amgtires()，因为没有它就可以完成。
我使用for循环创建了Radiobutton，使工作变得如此简单。

这是完整的代码。

import tkinter as tk
#make a new window
window10 = tk.Tk()
#lable what the page is
amgpage = tk.Label(window10, text="Mercedes Benz AMG Maintenance Calculator")
amgpage.pack(anchor='n')

#ask the user how many tires are needed
amgpage = tk.Label(window10, text="How many new tires do you need?")
amgpage.pack(anchor='w')

gr1=tk.IntVar()
tire_cost = tk.DoubleVar()

def amgtotal():
#open a new page
    window17 = tk.Toplevel()  # Use Toplevel instead of tk.

    #total cost for tires
    amgpage = tk.Label(window17, text="Tire Cost: $"+ str(tire_cost.get()) )
    amgpage.pack(anchor='w')

    #size for window
    window17.geometry("400x400")

    #window title   
    window17.title("Mercedes Benz AMG Maintenance Total")


#radio button on how many tire are needed
for i in range(4):
    tire = tk.Radiobutton(window10, text=i, variable = gr1, value=i)
    tire['command'] = lambda i=i : tire_cost.set( 227.9*i )
    tire.pack(anchor='w')

tire = tk.Radiobutton(window10, text="None", value=5, variable=gr1)
tire.pack(anchor='w' )

#Get the total cost for maintenace
amgpage = tk.Button(window10,text= "Get total cost", command = amgtotal,fg = 'Green')
amgpage.pack(anchor='w')

#size for window size
window10.geometry("700x400")

#window title       
window10.title("Mercedes Benz AMG Maintenance Calculator")

#end of window10 loop
window10.mainloop()

您可以使它变得更好，希望对您有所帮助。
