 Round numbers in [Python](https://4geeks.com/lesson/intro-to-python) is a very important operation since it is used in almost every field in programming to archive multiple goals. During this article, we will see several methods in python to round numbers such as round up, round down, round to a specific decimal number and round to the nearest integer number. Here is a code snippet that shows how to round a number in Python:

 To round a number to the nearest integer number, we can use the method `round()` in Python. This function only takes one number as parameter and it returns the number rounded:

 If we want to round a number to a specific amount of decimals, we can use second parameter in `round()` called `ndigits`. This parameter indicates how many decimals we want our number to be include:
