## Python List: Exercise - 96 with Solution

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

Sample Solution:

Python Code:

``````def sort_sublists(input_list):
input_list.sort()  # sort by sublist contents
input_list.sort(key=len)
return input_list

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]]
```

## Python: Tips of the Day

Floor Division:

When we speak of division we normally mean (/) float division operator, this will give a precise result in float format with decimals.

For a rounded integer result there is (//) floor division operator in Python. Floor division will only give integer results that are round numbers.

```print(1000 // 300)
print(1000 / 300)```

Output:

```3
3.3333333333333335```
