the book said,its using python 2.7.but i tried both 2.7 and 3.5.none of them working.whats wrong?
They are string format symbols. When you start your program, instead of %s it prints a string and instead of %d it prints an integer number
print("ip address: %s, port number: %d" % ("127.0.0.1", 80))
will print:
ip address: 127.0.0.1, port number: 80
