requests.exceptions.ConnectionError: ('Connection aborted.', gaierror(8, 'nodename nor servname provided, or not known'))

I am trying to check a file containing urls which will return a response status code 200. I am using python 3.7.1 Below is the code that I have used 

import requests
import sys
url_list = sys.argv[1]
with open(url_list) as fp:
    for line in fp:
        response = requests.get(line)
        if (response.status_code == '200'):
            print ("%s is up "%line)
        print (response.status_code)

Above code is triggering error

Urls of the file used to txt

The above urls when tested directly using requests.get("https://www.instagram.com") gives the desired output.

You should remove the trailing newline from the string:

import requests
import sys

url_list = sys.argv[1]
with open(url_list, 'r') as fp:
    for line in fp:
        url = line.rstrip()
        response = requests.get(url)
        if (response.status_code == 200):
            print ("%s is up " % url)
        print (response.status_code)
