In Python, you can index dictionaries using keys. A dictionary is a collection of key-value pairs, where each key is unique. You can access, modify, and delete elements using their keys.
<?php
// Example of indexing a dictionary in Python
my_dict = {'name': 'Alice', 'age': 30, 'city': 'New York'}
// Accessing a value using a key
print(my_dict['name']) // Output: Alice
// Modifying a value using a key
my_dict['age'] = 31
// Deleting a key-value pair
del my_dict['city']
?>
