Can I set timeout for the sys.stdin.readline() ?

Hi, I am new here.
When I use sys.stdin.readline() to get input string from user,
how can I set a timeout value for this operation?
thank you.

You can do a select() on sys.stdin, and put a timeout on the select, ie:

rfds, wfds, efds = select.select( [sys.stdin], [], [], 5)

would give you a five second timeout. If the timeout expired, then rfds
would be an empty list. If the user entered something within five
seconds, then rfds will be a list containing sys.stdin.

Note that by "user entered something", I mean they pressed
Enter/Return. The select will not exit if they just enter other text.

To my knowledge, this won't work on M$ Windows (which the original
