Python Question

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?

Answer

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.
