Removing Items
Lesson 7 of 14 in Coddy's Dictionary in Python course.
To remove a key-value pair from a dictionary use the del statement or the pop() method,
my_dict = {"name": "Alice", "age": 30, "city": "New York"}
del my_dict["city"] # Remove the "city" key-value pair
my_dict.pop("age") # Remove the "age" key-value pair
