One of the most common operations is rounding numbers to a specific decimal place. In this tutorial, you will learn how to round a number to 2 decimal places using Python.

**Step-by-Step Instructions**

*Define the number you want to round*

To round a number to 2 decimal places, you first need to define the number by assigning it to a variable. For example, if you want to round the number 3.14159 to 2 decimal places, you can do this by assigning the number to a variable like this:

`number = 3.14159`

*Use the round() function*

Python has a built-in function called `round()`

that you can use to round a number to a specific decimal place. To round the number to 2 decimal places, pass the number and the number of decimal places you want to round to as arguments to the `round()`

function. For example:

`rounded_number = round(number, 2)`

In this code, the first argument is the number you want to round and the second argument is the number of decimal places you want to round to.

*Print the rounded number*

After rounding the number, you can print it to the console using the `print()`

function:

`print(rounded_number)`

This will output the rounded number to the console.

**Options Available for the Round() Function**

The `round()`

function has some additional options that you can use to customize the rounding process.

*Rounding to the nearest even number*

By default, the `round()`

function rounds to the nearest number. You can also round to the nearest even number by passing an additional argument to the `round()`

function:

`rounded_number = round(number, 2, 'even')`

*Rounding up*

To round up to the nearest number, pass the value of -1 as the second argument to the `round()`

function:

`rounded_number = round(number, -1)`

*Rounding down*

To round down to the nearest number, pass the value of -2 as the second argument to the `round()`

function:

`rounded_number = round(number, -2)`

In this tutorial, you learned how to round a number to 2 decimal places using the built-in `round()`

function in Python. You also learned about some additional options available for the `round()`

function to customize the rounding process. With this knowledge, you can now perform rounding operations in Python with ease.
