当点击按钮时，程序运行一次，然后什么都不运行

Question

当我运行代码时，它只在我按下按钮时工作一次，但在那之后，当我再次按下按钮时，什么也没有发生。拜托，我是新手，所以请容忍我 下面是我的代码：

from Tkinter import*
import random

class Love:
    def __init__(self):
        window = Tk()
        window.title("Love Calculator")
        window.geometry("300x180")

        frame1 = Frame(window)
        frame1.pack()
        self.lbl = Label(frame1, fg="white", bg = "blue",            text = "Love is Pure" )
        self.lbl2= Label(frame1, fg="White", bg = "red", width="50", text = "are you meant for one another")
        self.lbl3= Label(frame1, fg="white", bg = "green",           text = "Let FIND OUT!!" )
        self.lbl.pack()
        self.lbl2.pack()
        self.lbl3.pack()

        frame2 = Frame(window)
        frame2.pack()
        label  = Label(frame2, text = "Your Name")
        label2 = Label(frame2, text = "Your Lovers name")

        self.msg = StringVar()
        entry1 = Entry(frame2, textvariable = self.msg)

        self.out = StringVar()
        entry2 = Entry(frame2, textvariable = self.out)

        btCalculate=Button(frame2, command=self.processButton, text="Calculate" )
        btClear=Button(    frame2, command=self.clear_textbox, text="Try Another Name" )

        label.grid(       row=1,column=1)          # .GUI-geometry
        label2.grid(      row=2,column=1)
        entry1.grid(      row=1,column=2)

Answer 1

根据我的测试，它运行了多次。问题似乎是，第一次运行Len时，它的值是11，之后每次都是77。这是因为你是从信息框计算Len1和Len2，而不是从输入框计算Len1和Len2，而信息11（友谊在永恒的风暴中奋力拼搏）正好是你再次计算时指向自己的字母数。你知道吗

你可以通过替换

    self.out=str(self.out)
    self.msg=str(self.msg)
    Len1 = len(self.out)
    Len2 =len(self.msg)

与

    entry1str=self.entry1.get()
    entry2str=self.entry2.get()
    Len1 = len(entry1str)
    Len2 =len(entry2str)

另外，当我在这里的时候，你需要使用自入口1以及自我介绍2在您使用entry1和entry2的大多数地方，否则框不会正确清除。你知道吗

希望有帮助！你知道吗
