How do I use dictionaries in Python?

Dictionaries in Python are used to store data values in key:value pairs. Would you like to see an example?

Yes, please show me a simple example.

Sure! Here's a basic example:

my_dict = {'name': 'Alice', 'age': 25}
print(my_dict['name'])  # Output: Alice

How can I add a new key-value pair to the dictionary?

You can add a new key-value pair like this:

my_dict['city'] = 'New York'

This will add 'city' as a key with 'New York' as its value.

What if I want to remove a key from the dictionary?

You can use the del statement to remove a key:

del my_dict['age']

This will remove the 'age' key from the dictionary.
