Within a simple `{}` block, we can round a float number with the necessary precision, or represent a number as a percent.

Let's consider the pattern we will use in this chapter:

`{:[thousands separator].[number][type]}`

Please note, that like in the previous chapters, we don't need to place square brackets (I placed it for convenience).
- `[thosands separator]` - the symbol used to separate every thousand (possible values are `,` and `_`).
- `[number]` - is the precision, number of decimal places (used for rounding number).
- `[type]` - type of number representing (`e` - scientific notation, `%` - percentage (will multiply number by 100), `g` - general format, `f` - fixed-point notation).
 You can dive deeper into possible options in Python documentation.

```
Input:
print("Original number: {0}, formatted number: {0:.2f}".format(255/8))
print("Original number: {0}, formatted number: {0:.2%}".format(15/48))
print("Original number: {0}, formatted number: {0:,.2f}".format(35*6327))

Output:
Original number: 31.875, formatted number: 31.88
Original number: 0.3125, formatted number: 31.25%
Original number: 221445, formatted number: 221,445.00
```
