Python: Sort a list of nested dictionaries

Sample Solution:-

Python Code:

my_list = [{'key': {'subkey': 1}}, {'key': {'subkey': 10}}, {'key': {'subkey': 5}}]
print("Original List: ")
my_list.sort(key=lambda e: e['key']['subkey'], reverse=True)
print("Sorted 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:


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}
