What are some examples of using dictionaries in Python?
Dictionaries in Python are used to store data values in key:value pairs. For example, you can create a dictionary like this: my_dict = {'name': 'Alice', 'age': 25}
.
Can you show me how to access values in a dictionary?
Sure! You can access values by using their keys. For example, my_dict['name']
will return 'Alice'.
How do I add a new key-value pair to an existing dictionary?
You can add a new key-value pair by simply assigning a value to a new key. For example, my_dict['city'] = 'New York'
.
What if I want to remove a key from the dictionary?
You can remove a key using the del
statement. For example, del my_dict['age']
will remove the 'age' key from the dictionary.
