redirecting Stdin

assume  we have a file :
after redirection   sys.stdin = file('newinput')

-----------------------------------
#newinput file 

import socket

def detectip():
    buf = socket.gethostname()
    remotehost = socket.gethostbyname(buf)
    return remotehost


if __name__ == "__main__":

    print "Your IP address is", detectip()
    raw_input()
------------------------

using 

line=sys.stdin:readline()
exec line

This results in a parsing error when the file reading reaches the
 def detectip(): 
sentence . 
You can execute the command line as long as it is a single line
command 

How to Get arround this ?

With regards 
JON
