You didn't include the full exception that you're getting, but my
guess is that the line trowing the error is the one calling input().
Move your try up before that line, and it should work as you expected.
On a slightly different note, input() isn't really the right function
to call here. input() evaluates python commands. Instead, use
raw_input() which just returns a user-entered string.
Something like this (untested):
sshport = raw_input('Port: ')
if sshport == "":
sshport = "2024"
try:
sshport = int(sshport)
except ValueError:
print "Not a valid port"
sys.exit()
cmd = 'su root -c "/usr/sbin/sshd -p %s"' % port
