In Python, you can round a number using the built-in `round()`

function. The `round()`

function takes two arguments: the number you want to round and the number of decimal places to round to. Here’s an example:

num = 3.14159 rounded_num = round(num, 2) print(rounded_num)

In this example, `num`

is the number you want to round and `2`

is the number of decimal places to round to. The output will be `3.14`

.

If the second argument is omitted, the `round()`

function will round to the nearest integer:

num = 3.7 rounded_num = round(num) print(rounded_num)

In this example, `num`

is `3.7`

and the `round()`

function rounds it to `4`

.
