@ -851,10 +851,11 @@ For integers, use the built-in :func:`int` type constructor, e.g. ``int('144')
e.g. ``float('144') == 144.0``.
By default, these interpret the number as decimal, so that ``int('0144') ==
144`` and ``int('0x144')`` raises :exc:`ValueError`. ``int(string, base)`` takes
the base to convert from as a second optional argument, so ``int('0x144', 16) ==
324``. If the base is specified as 0, the number is interpreted using Python's
rules: a leading '0o' indicates octal, and '0x' indicates a hex number.

Do not use the built-in function :func:`eval` if all you need is to convert
strings to numbers. :func:`eval` will be significantly slower and it presents a
