该程序运行一次，当按钮被点击，然后什么也没有

Question

当我运行它的代码只有一次，当我按下按钮，但之后，当我再次按下按钮没有反应。拜托，我这样的新手和我一起承担 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.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")

     window.mainloop()       # .GUI-control-loop 

    def clear_textbox(self,):      # .CMD callbackHANDLER

Answer 1

它是运行多次，根据我的测试。问题似乎是，你计算Len在你第一次运行时是11，然后是每次77。这是因为你正在从MESSAGE框中计算Len1和Len2，而不是从入口框计算出来，并且消息11（友谊力争通过永恒风暴）恰好是再次计算时指向自身的正确字母数。

您可以通过

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

而且更换

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

解决这个问题，当我在这里，你需要使用self.entry1和self.entry2在大部分的地方你已经使用了entry1和entry2，否则这些框不能正确清除。

希望有帮助！
