Answer 1

First of all you need to close your file, you can use with wrapper to make python take care of it for you. Remove the class line. Rest of the code looks fine.

import os

with open('D:/Workspace/snacks.txt', "r") as f:
    for line in f.readlines():
        if line.find('chocolate') != -1 or line.find('milkshake') != -1:
            print "found ", line
        else:
            print "not found" 

Answer 2

with open('foo') as f:
    lines = f.readlines()
    for line in lines:
        if 'chocolate' in line.lower():
            print "Found: ", line
        elif 'milkshake' in line.lower():
            print "Found: ", line
        else:
            print "Not Found."
