[Prudent]

New submission from Prudent <zongjsnt at aliyun.com>:

I am writing codes for opening file dialog to select a file by clicking a button. The function I used was "askopenfilename()" in tkinter.filedialog module. However, a warning displayed when I ran the code. And, the file filter option was also disabled after one click. The displayed warning was below.
