# Python: Sort a list of lists by length and value using lambda

## Python Lambda: Exercise-28 with Solution

Write a Python program to sort a given list of lists by length and value using lambda.

Sample Solution:

Python Code :

``````def sort_sublists(input_list):
result = sorted(input_list, key=lambda l: (len(l), l))
return result
list1 = [[2], [0], [1, 3], [0, 7], [9, 11], [13, 15, 17]]
print("Original list:")
print(list1)
print("\nSort the list of lists by length and value:")
print(sort_sublists(list1))
``````

Sample Output:

```Original list:
[[2], [0], [1, 3], [0, 7], [9, 11], [13, 15, 17]]

Sort the list of lists by length and value:
[[0], [2], [0, 7], [1, 3], [9, 11], [13, 15, 17]]
```
