Question

我想根据选中的单选按钮打印不同的文本。我的if语句应如何显示，以便我可以看到检查了哪个按钮？

from tkinter import *
from tkinter import ttk

myApp = Tk()
myApp.title("Cost Analysis")                         

RadioPlanned=Radiobutton(predictionframe1, text="option 1", value=1)
RadioPlanned.grid(row=0,column=0)

RadioReal=Radiobutton(predictionframe1, text="option 2", value=2)
RadioReal.grid(row=1,column=0)

def printing():

    if # radio button "option 1 " is checked
        print("option 1")

    elif # radio button "option 2 " is checked
        print("option 2")

but=Button(myApp, text="button", command=printing)
but.grid(row=2, column=0)

myApp.mainloop()

我找到了解决方案，这里是代码：

from tkinter import *

from tkinter import ttk

myApp = Tk()
myApp.title("Cost Analysis")                         

option=IntVar()

RadioPlanned=Radiobutton(myApp, text="option 1", value=1, variable=option)
RadioPlanned.grid(row=0,column=0)

RadioReal=Radiobutton(myApp, text="option 2", value=2, variable=option)
RadioReal.grid(row=1,column=0)

def printing():

    if option.get()==1:
        print("option 1")
    elif option.get()==2:
        print("option 2")

but=Button(myApp, text="button", command=printing)
but.grid(row=2, column=0)

myApp.mainloop()

根据Tkinter选中的单选按钮打印不同的行
