Python2.7Tkinter类

我试图用tkinter创建一个基类，它可以显示解析到它的任何变量的内容

我的目标是拥有多个类，这些类将变量传递给要显示的类。到目前为止，我有以下代码，但我无法使其按预期工作

任何帮助都将不胜感激，谢谢

from Tkinter import *

class interface:
    def __init__(self, root):
        root.title("Testing tkinter and labels")
        root.geometry("600x200")

    def text(str1, str2):
        Label(root, text = str1).pack(expand=1)
        Label(root, text = str2).pack(expand=1)

        app = Frame(root)
        app.pack(side = 'bottom')
        button1 = Button(app, text="Next")
        button1.pack()

str1 = "hello"
str2 = "bye"
root = Tk()
interface(root)
interface.text(str1, str2)
root.mainloop()

我想你应该有这个：

def text(self, str1, str2): #<-- you forgot self

应该是：

int_obj = interface(root) # you need to create a variable to hold an instance of the interface you create. Otherwise, its immediately deleted.
int_obj.text(str1, str2)

为什么它不起作用？有错误吗？

int_obj = interface(root) # you need to create a variable to hold an instance of the interface you create. Otherwise, its immediately deleted.
int_obj.text(str1, str2)
