First of all, both functions are returning a single value, a
of python closures. A lot of complex code gets written by
people who don't think of using an appropriate closure
- The 'with' statement.
- Properties.
I adapted this from here:

Also check out this StackOverflow question:

The way I would do this is as follows:
I would use itertools to make the code more concise. Also, a strong
recommendation that `with` should be used whenever you want to open a
file. And use of the `print_function` from `__future__` for python-3
compatibility.
