Python Forum

here is the code, some of it have been converted, so like it is not it will not run on ether one.

import socket   #for sockets
import sys  #for exit
 
try:
    #create an AF_INET, STREAM socket (TCP)
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
except socket.error as msg:
    print('Failed to create socket. Error code: {}'.format(str(msg)))
    sys.exit()
 
print ('Socket Created')
 
host = 'www.google.com'
port = 80
 
try:
    remote_ip = socket.gethostbyname( host )
 
except socket.gaierror:
    #could not resolve
    print ('Hostname could not be resolved. Exiting')
    sys.exit()
     
print ('Ip address of ') + host + ' is ' + remote_ip
 
#Connect to remote server
s.connect((remote_ip , port))
 
print ('Socket Connected to ') + host + ' on ip ' + remote_ip

I think this part is the problem:

print ('Ip address of ') + host + ' is ' + remote_ip
 
#Connect to remote server
s.connect((remote_ip , port))
 
print ('Socket Connected to ') + host + ' on ip ' + remote_ip

I been looking for a place that show the 2.7 commands = the 3.5, I have not found any thing like that yet.

What way is the best to convert the code?

I try to edit this but could find a way.

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.

Ip address of 
Traceback (most recent call last):

 File "<interactive input>", line 1, in <module>

# 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

I don't need a port? =  port = 80
what is a  remote_ip = '111.111.111, that only have 3 set of numbers, most ip have 4 set of numbers 111.111.111.111?

This having two type of code is driving me crazy.
You can see that I want to play around with bots. Is the a good tut. in 3.5 on making bots. I don't care what kinds, right now just want to get basic down and learned, then I can go from their?

It could have been any number,i was just showing what was wrong with this line:

print ('Ip address of ') + host + ' is ' + remote_ip # ) wrong placement

The correct and best way:

print('Ip address of {} is {}'.format(host, remote_ip))

Have you not look into now how interactive interpreter work?


You can try this code:

import socket   
import sys

try:    
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
except socket.error as msg:
    print('Failed to create socket. Error code: {}'.format(str(msg)))
    sys.exit()

print('Socket Created')
host = 'www.google.com'
port = 80

try:
    remote_ip = socket.gethostbyname(host)
except socket.gaierror:
    print('Hostname could not be resolved. Exiting')
    sys.exit()

print('Ip address of {} is {}'.format(host, remote_ip))
s.connect((remote_ip , port))
print('Socket Connected to {} on ip {}'.format(host, remote_ip))

Ok, that does work, I found a place that have a lot of the commands for 3.5.2 . I hope I can start to get my mind warped around this.
Thank you
