Python: Sort a list of lists by length and value
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
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))
