Python tkinter单选按钮不会更改变量

Question

我尝试在python3.4.3中使用单选按钮，而这些单选按钮不会更改其指定的变量。我错过了什么？在

from tkinter import *
import tkinter

class c:
def __init__(self):
    self.master=tkinter.Tk()
    self.bvar=IntVar()
    rb1=Radiobutton(self.master,text="1",variable= self.bvar,value=1,command=self.rbselect).pack()
    rb2=Radiobutton(self.master,text="0",variable=self.bvar,value=0,command=self.rbselect).pack()

def rbselect(self):
    print(self.bvar)

def run(self):
    self.master.mainloop()

app=c()
app.run()

Answer 1

需要使用.get（）来比较IntVar实例：

from tkinter import *
import tkinter

class c:
    def __init__(self):
        self.master=tkinter.Tk()
        self.b=IntVar() 
        rb1=Radiobutton(self.master,text="1",variable= self.b,value=1,command=self.rbselect).pack()
        rb2=Radiobutton(self.master,text="0",variable= self.b,value=0,command=self.rbselect).pack()

    def rbselect(self):
        print(self.b.get())

    def run(self):
        self.master.mainloop()

app=c()
app.run()
