What are the different data types in Python and how do I use them?

Python has several built-in data types, including integers, floats, strings, lists, tuples, sets, and dictionaries. Each serves different purposes.

Can you give me examples of how to use lists and dictionaries?

Sure! A list can be created like this: my_list = [1, 2, 3]. You can access elements using indices. A dictionary is created like this: my_dict = {'key': 'value'} and you access values using keys.

What about tuples? How are they different from lists?

Tuples are similar to lists but are immutable, meaning once created, their elements cannot be changed. You create a tuple like this: my_tuple = (1, 2, 3).

When should I use a set instead of a list?

Use a set when you need to store unique elements and don't care about the order. Sets are also faster for membership tests.
