## Reverse a List python

### Sorting a List Permanently with the sort() Method

Python’s `sort()`

method makes it relatively easy to sort a list. Imagine we have a list of student names and want to change the order of the list to store them alphabetically.

`students = ['benny', 'alice', 'tony', 'sam'] students.sort() print(students)`

The `sort()`

method, changes the order of the list permanently. The students are now in alphabetical order, and we can never revert to the original order.

`# ['alice', 'benny', 'sam', 'tony']`

## How to Reverse a List in Python

You can also sort this list in reverse alphabetical order by passing the argument `reverse=True`

to the `sort()`

method.

`students = ['benny', 'alice', 'tony', 'sam'] students.sort(reverse=True) print(students)`

Again, the order of the list is permanently changed

`['tony', 'sam', 'benny', 'alice']`

### Sorting a List Temporarily with the sorted() Function

To maintain the original order of a list but present it in a sorted order, you can use the `sorted()`

function. The `sorted()`

function lets you display your list in a particular order but doesn’t affect the actual order of the list.

`students = ['benny', 'alice', 'tony', 'sam'] print("Here is the original list:") print(students) print("\nHere is the sorted list:") print(sorted(students))`

`Here is the original list: ['benny', 'alice', 'tony', 'sam'] Here is the sorted list ['alice', 'benny', 'sam', 'tony']`

Notice that the list still exists in its original order after the `sorted()`

function has been used. The `sorted()`

function can also accept a `reverse=True`

argument if you want to display a list in reverse alphabetical order.

### Printing a List in Reverse Order

To reverse the original order of a list, you can use the `reverse()`

method.

`students = ['benny', 'alice', 'tony', 'sam'] print(students) students.reverse() print(students)`

The `reverse()`

doesn’t sort backward alphabetically.It simply reverses the order of the list.

`['benny', 'alice', 'tony', 'sam'] ['sam', 'tony', 'alice', 'benny']`
