Python | Sort lists in tuple
• Last Updated : 14 May, 2020

Sometimes, while working with Python tuples, we can have a problem in which we need to sort the tuples which constitutes of lists and we need to sort each of them. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using `tuple() + sorted()` + generator expression
This task can be performed using the combination of above functions. In this, we iterate through each list using generator expression and perform the sort operation using `sorted()`.

 `# Python3 code to demonstrate working of ` `# Sort lists in tuple ` `# Using tuple() + sorted() + generator expression ` ` `  `# Initializing tuple ` `test_tup ``=` `([``7``, ``5``, ``4``], [``8``, ``2``, ``4``], [``0``, ``7``, ``5``]) ` ` `  `# printing original tuple ` `print``(``"The original tuple is : "` `+` `str``(test_tup)) ` ` `  `# Sort lists in tuple ` `# Using tuple() + sorted() + generator expression ` `res ``=` `tuple``((``sorted``(sub) ``for` `sub ``in` `test_tup)) ` ` `  `# printing result ` `print``(``"The tuple after sorting lists : "` `+` `str``(res)) `

Output :

```The original tuple is : ([7, 5, 4], [8, 2, 4], [0, 7, 5])
The tuple after sorting lists : ([4, 5, 7], [2, 4, 8], [0, 5, 7])
```

Method #2 : Using `map() + sorted()`
This method performs the similar task as the above method, but it uses `map()` to extend the logic to each element of tuple, the task performed by list comprehension in above method.

 `# Python3 code to demonstrate working of ` `# Sort lists in tuple ` `# Using map() + sorted() ` ` `  `# Initializing tuple ` `test_tup ``=` `([``7``, ``5``, ``4``], [``8``, ``2``, ``4``], [``0``, ``7``, ``5``]) ` ` `  `# printing original tuple ` `print``(``"The original tuple is : "` `+` `str``(test_tup)) ` ` `  `# Sort lists in tuple ` `# Using map() + sorted() ` `res ``=` `tuple``(``map``(``sorted``, test_tup)) ` ` `  `# printing result ` `print``(``"The tuple after sorting lists : "` `+` `str``(res)) `

Output :

```The original tuple is : ([7, 5, 4], [8, 2, 4], [0, 7, 5])
The tuple after sorting lists : ([4, 5, 7], [2, 4, 8], [0, 5, 7])
```
