Python List: Exercise - 55 with Solution
Write a Python program to remove key-value pairs from a list of dictionaries.

Sample Solution:-
Python Code:
original_list = [{'key1':'value1', 'key2':'value2'}, {'key1':'value3', 'key2':'value4'}]
print("Original List: ")
print(original_list)
new_list = [{k: v for k, v in d.items() if k != 'key1'} for d in original_list]
print("New List: ")
print(new_list)
Sample Output:
Original List: [{'key1': 'value1', 'key2': 'value2'}, {'key1': 'value3', 'key2': 'value4'}] New List: [{'key2': 'value2'}, {'key2': 'value4'}]

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))
