Finding websites IP through reading lines

i am trying to achieve a task that a script can load a file and iterate through lines and finding domain ip from each line.

Tried doing it with this code:

import socket

with open('test.txt','r') as f:
for i in f.readlines():
i.strip('n')
i.strip('t')
i.strip('r')
print(socket.gethostbyname(i))

f.close()


But shows error

Traceback (most recent call last): File "ip.py", line 8, in
print(socket.gethostbyname(i)) socket.gaierror: [Errno -2] Name or service not known

Any help would be appreciated.

Thanks

The issue is that string.strip doesn't modify the string, rather, from the documentation:

string.strip

Return a copy of the string with leading and trailing characters removed.

Therefore, you can do something like the following:

import socket

with open('test.txt','r') as f:
for i in f.readlines():
i = i.strip('n')
i = i.strip('t')
i = i.strip('r')
print(socket.gethostbyname(i))

f.close()


Running that on a test.txt that looks like:

test.txt

test.com
google.com
yahoo.com


I get:

69.172.200.235
172.217.26.110
98.138.219.232


problem solved.

I wasn't saving the split result in my i variable which was not removing the new line character after each domain..
Appreciate every comments.

Thanks

Can you try below. it worked.
Issue is like you might be having other strings too apart from host name which might be throwing exception.

import socket

a = ['word2','www.google.co.in','word3']
for i in a:
try:
i.strip('n')
i.strip('t')
i.strip('r')
print(socket.gethostbyname(i))
except socket.gaierror:
print("Unable to get Hostname and IP")


Output:

Unable to get Hostname and IP
172.217.195.94
Unable to get Hostname and IP
