Changing Dictionary Items

Dictionary items are mutable; you can change the value of a specific item by referring to its key name.

Modifying Existing Items

# Changing a dictionary item
person = {"name": "John", "age": 26, "city": "Mumbai"}
person["age"] = 27
print("Updated Person:", person)

Updated Person: {'name': 'John', 'age': 27, 'city': 'Mumbai'}

Updating Multiple Items

Example: Using update() Method

# Updating multiple dictionary items
person.update({"age": 28, "city": "Delhi"})
print("Person after update:", person)

Person after update: {'name': 'John', 'age': 28, 'city': 'Delhi'}
