tkFileDialog有两种形式:
一个是.askopenfilename(option=value, ...) 这个是"打开"对话框
另一个是:asksaveasfilename(option=value, ...) 这个是另存为对话框
option参数如下:
defaultextension = s 默认文件的扩展名
filetypes = [(label1, pattern1), (label2, pattern2), ...] 设置文件类型下拉菜单里的的选项
initialdir = D 对话框中默认的路径
initialfile = F 对话框中初始化显示的文件名
parent = W 父对话框(由哪个窗口弹出就在哪个上端)
title = T 弹出对话框的标题
如果选中文件的话,确认后会显示文件的完整路径,否则单击取消的话会返回空字符串
