How do i send a file with sockets in python?

I am already familiar with python and socket usage and can send strings of text over these. But how would i go ab开发者_JAVA技巧out sending, say, an MP3 file?

The following code would do what you literally ask (assuming thesocket is a connected stream socket):

with open('thefile.mp3', 'rb') as f:
    thesocket.sendall(f.read())

but of course it's unlikely to be much use without some higher-level protocol to help the counterpart know how much data it's going to receive, what type of data, and so forth.
