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