This opens the file and reads all the lines but it
doesn't store the result anywhere so you just throw
those lines away.

The recommended way to do this in Python nowadays is:

with open('filename.txt') as infile:
    for line in infile:
       # process line here

file is a file object you cannot index into it using [2].

But even if you had used readlines and stored the result
checking line by line as shown above is probably a
better approach.
