Depends. I don't believe the original post mentioned that the file is a pipe, socket or similar, but it's kind of implied by the use of select() also mentioned. It's also kind of implied by use of the term "block" - disk files don't block. If we are indeed talking about a pipe or something that really can block, and you call fileobject.read(1024), it will block until it gets 1024 bytes.
