wxpython下输出错误到控制台console

wxpython用来创建窗口应用程序，但有时候我们希望能在控制台输出一些异常或者错误提示，这段代码能够帮助你实现

import sys
STDERR = sys.stderr  # Keep stderr because wxPyhon will redirect it.
import wx
[...your wxPython program goes here...]
if __name__ == "__main__":
    import traceback,sys
    try:
        app = MyWxApplication()  # Start you wxPython application here.
        app.MainLoop()
    except:
        traceback.print_exc(file=STDERR)
