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)]
