How to get a file descriptor number? Wow, this must be at least the 4th post of the same question. It now occurs to me that a newer Python won't help you. Are you running this at a command prompt? Or are you running this in some IDE? The reason I ask this question is that at a command prompt, the above would probably work. In short, please provide more context. What OS? What version of Python? What environment (command prompt, IDE (which one?), a standalone script, etc)?
