Python

import sys
import socket
import time
ip=([(s.connect(('8.8.8.8', 80)), s.getsockname()[0], s.close()) for s in [socket.socket(socket.AF_INET, socket.SOCK_DGRAM)]][0][1])


x="........"

def print_word_slowly(word):
    for i in word:
        sys.stdout.write(i)
        sys.stdout.flush()
        time.sleep(0.2)
        
        
        
print "Loading...\n"
print print_word_slowly("obtaining IP address......."), "     \nIP Address obtained. IP Address is %s."%(ip)

This prints out:

Loading...                                                                                                                               
                                                                                                                                         
obtaining IP address.......None                                                                                                          
IP Address obtained. IP Address is 172.17.29.xxx.

How can I get rid of 'None' after 'obtaining IP address.....'?

The issue is down to the hidden return value from a Python function. If a function does not include a return statement, then it automatically adds one, and returns the value None, as described in https://docs.python.org/3.3/reference/simple_stmts.html#index-21[^]. So your print statement calls the function, which prints the message, then gets the return value of None and prints that, before printing the remainder of its parameters.

You should delete the first "Print" before your "print_word_slowly() function".
Try call your function directly rather than "Print" it.
