Just to be clear, these don't do nearly the same thing in general,
though in your specific case they might appear similar.
The line[:-1] idiom says 'return a string which is a copy of the
original but with the last character, if any, removed, regardless of
what character it is'.
The line.strip() idiom says 'return a string with all whitespace
characters removed from the end *and* start of the string'.
In certain cases, you might reasonably prefer .rstrip() (which removes
only from the right-hand side, or end), or even something like
.rstrip('\n') which would remove only newlines from the end.
