An example of an AI chatbot conversation about hash maps and dictionaries in Python.
What is the difference between a hash map and a dictionary in Python?
In Python, a dictionary is a built-in data type that implements a hash map. They both store key-value pairs, but dictionaries are optimized for Python's use.
Are there any performance differences between them?
Yes, dictionaries in Python are highly optimized for performance, while hash maps can vary in implementation across different languages.
Can I use a list as a key in a dictionary?
No, lists are mutable and cannot be used as keys in a dictionary. You can use tuples instead, as they are immutable.
What are some common use cases for dictionaries in Python?
Dictionaries are commonly used for storing data that needs to be accessed via unique keys, such as user profiles, configuration settings, and more.
