Write a Python program to remove key values pairs from a list of dictionaries.

Python: Remove key values 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'}]
