# Python | Sort tuple list by Nth element of tuple

Sometimes, while working with Python list, we can come across a problem in which we need to sort list according to any tuple element. These must be a generic way to perform the sort by particular tuple index. This has a good utility in web development domain. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using `sort() + lambda`
The combination of above functions can be used to perform this task. In this, we just pass a lambda function to `sort()` with appropriate tuple element index according to which sort has to be performed.

 `# Python3 code to demonstrate working of ` `# Sort tuple list by Nth element of tuple ` `# using sort() + lambda ` ` `  `# initializing list ` `test_list ``=` `[(``4``, ``5``, ``1``), (``6``, ``1``, ``5``), (``7``, ``4``, ``2``), (``6``, ``2``, ``4``)] ` ` `  `# printing original list ` `print``(``"The original list is : "` `+` `str``(test_list)) ` ` `  `# index according to which sort to perform ` `N ``=` `1` ` `  `# Sort tuple list by Nth element of tuple ` `# using sort() + lambda ` `test_list.sort(key ``=` `lambda` `x: x[N]) ` ` `  `# printing result  ` `print``(``"List after sorting tuple by Nth index sort : "` `+` `str``(test_list)) `

Output :

```The original list is : [(4, 5, 1), (6, 1, 5), (7, 4, 2), (6, 2, 4)]
List after sorting tuple by Nth index sort : [(6, 1, 5), (6, 2, 4), (7, 4, 2), (4, 5, 1)]
```

Method #2 : Using `sort() + itemgetter()`
This is similar to the above method. The difference is just that we use `itemgetter()`, to perform this task that is done by lambda in above method.

 `# Python3 code to demonstrate working of ` `# Sort tuple list by Nth element of tuple ` `# using sort() + itemgetter() ` `from` `operator ``import` `itemgetter ` ` `  `# initializing list ` `test_list ``=` `[(``4``, ``5``, ``1``), (``6``, ``1``, ``5``), (``7``, ``4``, ``2``), (``6``, ``2``, ``4``)] ` ` `  `# printing original list ` `print``(``"The original list is : "` `+` `str``(test_list)) ` ` `  `# index according to which sort to perform ` `N ``=` `1` ` `  `# Sort tuple list by Nth element of tuple ` `# using sort() + itemgetter() ` `test_list.sort(key ``=` `itemgetter(N)) ` ` `  `# printing result  ` `print``(``"List after sorting tuple by Nth index sort : "` `+` `str``(test_list)) `

Output :

```The original list is : [(4, 5, 1), (6, 1, 5), (7, 4, 2), (6, 2, 4)]
List after sorting tuple by Nth index sort : [(6, 1, 5), (6, 2, 4), (7, 4, 2), (4, 5, 1)]
```
