How to make python check if a string lets say text1 is in this file?

Question

I thought it might look like this but I am unsure:

example = open("example.txt","r")

if example #has text1 in it then#: <-- What do I need to put between the #'s for the code to work?

Answer 1

import re
wordChk = re.compile(r'(.*)?text1(.*)?')
fileName=open("d:/foo.bar")
lines = [i for i in fileName.readlines()]
for x in lines:
    if wordChk.match(x):
        do something
