Maximum and Minimum values for ints
...bits in a word will be math.log2(sys.maxsize * 2 + 2). See this answer for more information.
Python 2

You can calculate the minimum value with -sys.maxint - 1 as shown her...
When to use ' (or quote) in Lisp?
...nly want to evaluate small parts of the code returned, so the backquote is more suited. For shorter lists, list can be more readable.

}
