Fairly obviously, you need to trim the line-feed characters off the lines
returned by the readlines() method.  I'm not sure why you are mapping the
str() function on the lines, since I would expect that they are strings
already.  But since you have a map call in there, why not map the
string.rstrip() function instead?

A more 2.0-ish way, since you're abviously prepared to read the whole file
in all at once, would be to use the splitlines() string method on a read()
of the file.  This would make the last line of your getTheLines() function

    return file.read().splitlines()

Either of these should suit.
