Python List: Exercise - 50 with Solution
Write a Python program to sort a list of nested dictionaries.
Sample Solution:-
Python Code:
my_list = [{'key': {'subkey': 1}}, {'key': {'subkey': 10}}, {'key': {'subkey': 5}}]
print("Original List: ")
print(my_list)
my_list.sort(key=lambda e: e['key']['subkey'], reverse=True)
print("Sorted List: ")
print(my_list)
Sample Output:
Original List:
[{'key': {'subkey': 1}}, {'key': {'subkey': 10}}, {'key': {'subkey': 5}}]
Sorted List:
[{'key': {'subkey': 10}}, {'key': {'subkey': 5}}, {'key': {'subkey': 1}}]

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))
