In this post, let's take a quick look at the `format()` method in Python.

## What is `.format()`?

`.format()` is a special function in Python that is used with `print()` to customize the output format easily.  

### Example

Consider the below code, 

```python
a = 10
b = 20
c = 30
```
We want to print the output like below,
```python
10 + 20 - 30 = 0
```
Generally we would do something like below,

```python
print(a,"+",b,"-",c,"=",a+b-c)
```
This works fine! but it's boring and looks more complex than a Christopher Nolan film. This is not Python known for!

Here comes the `format()` function.

Using `format()` the above can be achieved as below,

### Type 1

```python
print("{} + {} - {} = {}".format(a,b,c,a+b-c))
```
That's it! this looks much better than the original implementation.

### Type 2

We can also specify the index position for the format method if you want,

```python
print("{0} + {1} - {2} = {3}".format(a,b,c,a+b-c))
```
The first argument in the `format()` will replace the `{0}` and the second argument in `format()` will replace `{1}` and so on.

### Type 3

We can also use keywords instead of index.
```python
print("{0} + {1} - {2} = {res}".format(a,b,c, res = a+b-c))
```
Here, the `res` will be replaced by its definition.
