Comparing two files contents in python

Question

I have 2 text files and I want to compare content of one with another. Need to check ip in Unique.txt is present or not in CheckIp.txt. My code looks like:

with open("/root/nix_bsd_mac_inventory-master/Unique.txt") as fp:
    for line in fp:
        print(line)
        with open("/root/nix_bsd_mac_inventory-master/CheckIp.txt") as fp1:
            for line1 in fp1:
                line1 = line1.rstrip()
                if line == line1:
                    print (line1 + "Ip is Already Present")
                else:
                    print ("Processing Ip:"+ line)

It seems something I am doing wrong. Can someone please help me?

Considering your file "Unique.txt" does just containt the IP you're looking for:

f1 = open('CheckIp.txt', 'r')
data= ''.join(f1.readlines())
f2 = open('Unique.txt','r')
toFind = f2.readline()
if data.find(toFind) != -1:
    print("ip "+toFind+" found!")
else:
    print("ip "+toFind+" not found!")
