Question: I dont know much about python and am learning.

I have a variable like this,

```

I want to reduce the numbers after dot. Like, i have mentioned below

```
a = 23.35

```

Please help me.

Answer: 
you can use `round`

```
round(a, 2)

```

you can read more about it here [here](http://docs.python.org/2/library/functions.html#round)
You can do it this way:

```
a = float("{0:.2f}".format(a))

```
