Calling select in python

Question

I am trying to write a socket server. The server itself doesn\'t accomplish anything all that interesting. Right now my problem is that python is complaining about my arguments

Answer 1

You need to pass in three sequences of file descriptors as arguments to select, from the names you supply I think that [clients, signals] might be some other construct (is clients a list of file descriptors?). In this case you could use clients+signals as second argument to select.

In other words: Each argument must be a flat sequence, no nesting is allowed.
