Division in Python 2.7. and 3.3

How can I divide two numbers in Python 2.7 and get the result with decimals?

I don't get it why there is difference:

in Python 3:

    >>> 20/15
    1.3333333333333333

in Python 2:

    >>> 20/15
    1

Isn't this a modulo actually?

In python 2.7, the / operator is integer division if inputs are integers.

If you want float division (which is something I always prefer), just use this special import:

    from __future__ import division

See it here:

    >>> 3 / 2
    1
    >>> from __future__ import division
    >>> 3 / 2
    1.5
    >>>

Integer division is achieved by using //, and modulo by using %

    >>> 3 % 2
    1
    >>> 3 // 1
    3
    >>>

EDIT

As commented by user2357112, this import has to be done before any other normal import.
