Python 2.71.11 Tkinter窗口不关闭“应用程序没有响应”

Question

我想打开一个简单的文件对话框来要求用户选择一个文件。我的代码是：

from Tkinter import Tk 
from tkFileDialog import askopenfilename 

Tk().withdraw() 
filename = askopenfilename() 
print(filename) 
sys.exit(0) 

该程序成功检索文件名，但该窗口保持打开状态并且不关闭。我可以退出它的唯一方法是通过Force Quit。我正在使用Mac OS X 10.11和Python 2.7.11。

谢谢

Answer 1

似乎是基于你的开发环境的一些问题。参见参考文献[2]。这为我工作：

from Tkinter import Tk 
from tkFileDialog import askopenfilename 

root = Tk() #To initialize Tkinter, we have to first create a Tk root widget 
filename = askopenfilename() # store filename 
# root.mainloop() may be necessary for your development environment (see [2]) 
root.destroy() #destroy the event loop - only required in some python environments (see [2]) 
print(filename)
