Python syntax error while taking an IP address as an input

Question

I have a text file called sample_ips.txt containing some random IP addresses as follows:-

182.0.0.15
182.0.0.16
182.0.0.17

I am giving an IP ad

Answer 1

Well, this works:

input = raw_input("Enter IP:")
ip = open("sample_ips.txt", "r")
data = ip.readlines()
for ips in data:
    ips = ips.strip("\n")
    if input in ips:
        print "true"
    else:
        print "false"

:edit:

Python3 version

input = input("Enter IP:")
ip = open("sample_ips.txt", "r")
data = ip.readlines()
for ips in data:
    ips = ips.strip("\n")
    if input in ips:
        print ("true")
    else:
        print ("false")

Answer 2

input_ip = raw_input("Enter IP:") # In python 2.x. If you use input() then type your inputs as string (>>Enter IP:"182.0.0.15")
#input_ip = input("Enter IP:")  for python 3.x

with open("ip.txt", "r") as ip:
    data = ip.readlines()
    for ips in data:
        ips = ips.strip("\n")
        if input_ip in ips:
            print ("true")
        else:
            print ("false")
