Question

我试图打开一个简单的文件对话框，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)

程序成功检索文件名，但窗口保持打开状态且未关闭。我退出它的唯一方法是通过Force Quit。我使用的是Mac OS X 10.11和Python 2.7.11。

谢谢

根据您的开发环境，似乎存在一些问题。见参考文献[2]。这对我有用：

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)

Python 2.71.11 Tkinter窗口未关闭＆＃34;应用程序无响应＆＃34;
