## 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 = [, , [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:
[, , [1, 3], [0, 7], [9, 11], [13, 15, 17]]

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

## Python: Tips of the Day

Given a predicate function, fn, and a prop string, this curried function will then take an object to inspect by calling the property and passing it to the predicate:

Example:

```def tips_check_prop(fn, prop):
return lambda obj: fn(obj[prop])
check_age = tips_check_prop(lambda x: x >= 25, 'age')
user = {'name': 'Owen', 'age': 25}

print(check_age(user))
```

Output:

```True
```
