Given a Tuple List sort tuples by maximum element in a tuple.

Input: test_list = [(4, 5, 5, 7), (1, 3, 7, 4), (19, 4, 5, 3), (1, 2)]Output: [(19, 4, 5, 3), (4, 5, 5, 7), (1, 3, 7, 4), (1, 2)]Explanation: 19 > 7 = 7 > 2, is order, hence reverse sorted by maximum element.

Input: test_list = [(4, 5, 5, 7), (19, 4, 5, 3), (1, 2)]Output: [(19, 4, 5, 3), (4, 5, 5, 7), (1, 2)]Explanation: 19 > 7 > 2, is order, hence reverse sorted by maximum element.

**Method #1 : Using ****max()**** + ****sort()**

In this, we perform task of getting maximum element in tuple using max(), and sort() operation is used to perform sort.

## Python3

`# Python3 code to demonstrate working of ` `# Sort Tuples by Maximum element` `# Using max() + sort()` ` ` `# helper function` `def` `get_max(sub):` ` ` `return` `max` `(sub)` ` ` `# initializing list` `test_list ` `=` `[(` `4` `, ` `5` `, ` `5` `, ` `7` `), (` `1` `, ` `3` `, ` `7` `, ` `4` `), (` `19` `, ` `4` `, ` `5` `, ` `3` `), (` `1` `, ` `2` `)]` ` ` `# printing original list` `print` `(` `"The original list is : "` `+` `str` `(test_list))` ` ` `# sort() is used to get sorted result` `# reverse for sorting by max - first element's tuples` `test_list.sort(key ` `=` `get_max, reverse ` `=` `True` `)` ` ` `# printing result ` `print` `(` `"Sorted Tuples : "` `+` `str` `(test_list))` |

**Output:**

The original list is : [(4, 5, 5, 7), (1, 3, 7, 4), (19, 4, 5, 3), (1, 2)]

Sorted Tuples : [(19, 4, 5, 3), (4, 5, 5, 7), (1, 3, 7, 4), (1, 2)]

**Method #2 : Using sort() +**** lambda**** + reverse**

In this, we use similar functionality, the only difference here being use of lambda fnc. rather than external function for task of getting reverse sorting.

## Python3

`# Python3 code to demonstrate working of ` `# Sort Tuples by Maximum element` `# Using sort() + lambda + reverse` ` ` `# initializing list` `test_list ` `=` `[(` `4` `, ` `5` `, ` `5` `, ` `7` `), (` `1` `, ` `3` `, ` `7` `, ` `4` `), (` `19` `, ` `4` `, ` `5` `, ` `3` `), (` `1` `, ` `2` `)]` ` ` `# printing original list` `print` `(` `"The original list is : "` `+` `str` `(test_list))` ` ` `# lambda function getting maximum elements ` `# reverse for sorting by max - first element's tuples` `test_list.sort(key ` `=` `lambda` `sub : ` `max` `(sub), reverse ` `=` `True` `)` ` ` `# printing result ` `print` `(` `"Sorted Tuples : "` `+` `str` `(test_list))` |

**Output:**

The original list is : [(4, 5, 5, 7), (1, 3, 7, 4), (19, 4, 5, 3), (1, 2)]

Sorted Tuples : [(19, 4, 5, 3), (4, 5, 5, 7), (1, 3, 7, 4), (1, 2)]
