# How to Sort a List or Tuple

The`sorted()`

built-in function takes an iterable object and returns a list with the elements ordered from lowest to highest. The order criterion is defined by a `key`

function that assigns a numerical value to each element.`>>> sorted([2, 3, 1])`

[1, 2, 3]

The

`reverse`

parameter can be used to order results from highest to lowest.`>>> sorted([2, 3, 1], reverse=True)`

[3, 2, 1]

The

`key`

argument must be a function that takes an element and returns a numerical value that will be considered to order that element with respect to the rest. For example, to sort a list of strings from smallest to largest based on the number of characters, use the built-in `len()`

function:`>>> sorted(["Python", "Java", "C", "C++"], key=len)`

['C', 'C++', 'Java', 'Python']

The same way, the following code puts the even numbers at the beginning of the list and the rest at the end.

`>>> def is_even(n):`

... return n % 2 == 0

...

>>> sorted(range(10), key=is_even, reverse=True)

[0, 2, 4, 6, 8, 1, 3, 5, 7, 9]

Because

`is_even(n)`

returns `True`

(`1`

) if `n`

is even and `False`

(`0`

) otherwise.🐍 You might also find interesting:
