Adding Items

Lesson 6 of 14 in Coddy's Dictionary in Python course.

To add an item to a dictionary use a new key and assign a value to it,

my_dict = {"name": "Alice", "age": 30, "city": "New York"}
my_dict["country"] = "USA"  # Add a new key-value pair

The same can be done using update method as we seen last lesson,

my_dict.update({"country": "USA"})
