how to make the program notify me explicitly

[hankssong]

Hi everyone, I'm writing a program that can retrieve some specified
info from a web page, such as python topics I interested  on a bbs.
Now I had written the python script (run in the background), but I
don't know how to make the program notify me explicitly, so I can be
easily informed. I don't know whether python can warn me through
beeping like C program(e.g.:printf("%c", '\07');)
Thanks in advance!
