python - Comparing equal strings returns False?

Question

So I'm making a basic makeshift login validate thing with just a basic text file to "pretend" and what should return True is not. The username check works but not the password check

@staticmethod
def validate_login(filename,username,password):
    file = open(filename,'r')
    file.readline()
    for line in file:
        i = [i for i, char in enumerate(line) if char == '|']
        print username == line[i[0] + 2:i[1]-1]
        print password == line[i[1] + 2:]
        print password
        print line[i[1] + 2:]
        if username == line[i[0] + 2:i[1]-1] and password == line[i[1] + 2:]:
            file.close()
            print "Login Successful."
            return True

    file.close()
    print "Failed to login. Invalid username or password."
    return False

This is the output result. The password matches exactly with the text file yet returns false. The username returns true.What exactly is the issue?? It is driving me insane.

True <--- username matched correctly returns true
False <---passwords apparently don't match, returns false.

You likely have a newline \n in your password comparison. You will need to strip() it off. Any reason not to use split, e.g. u, p = line.strip().split('|'); if username == u and password == p): ... — AChampion

Had to use .strip() function to remove unforeseen characters at the end of the line.
