POSTing a file requires multipart/form-data encoding and, as far as I know, there's no easy way (i.e. one-liner or something) to do this with the stdlib. But as you mentioned, there are plenty of recipes out there.

Although they seem verbose, your use case suggests that you can probably just encapsulate it once into a function or class and not worry too much, right? Take a look at the recipe on ActiveState and read the comments for suggestions:

• Recipe 146306: Http client to POST using multipart/form-data

or see the MultiPartForm class in this PyMOTW, which seems pretty reusable:

• PyMOTW: urllib2 - Library for opening URLs.

I believe both handle binary files.
