What way is the best to convert the code?

Actually knowing Python help
and what's the difference is between 2 and 3 it's not so much work to convert short code like this.
Use 2to3 it dos a pretty good job.

I think this part is the problem:

>>> host = 'google.com'
>>> remote_ip = '111.111.111'
>>> print ('Ip address of ') + host + ' is ' + remote_ip
Ip address of 
Traceback (most recent call last):
 File "<string>", line 301, in runcode
 File "<interactive input>", line 1, in <module>
TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'

# Fix
>>> print('Ip address of ' + host + ' is ' + remote_ip)
Ip address of google.com is 111.111.111

>>> # Better
>>> print('Ip address of {} is {}'.format(host, remote_ip))
Ip address of google.com is 111.111.111
