Python Tuples, Sets, Dictionaries, and Ranges
Learning Objective
I can compare and contrast tuples, sets, dictionaries, and ranges in Python.
Key Concepts
The key difference between a list and a tuple in Python is that tuples are immutable, meaning they cannot be changed after creation, while lists are mutable.
Because tuples are immutable, they are stored in one block of memory, making them faster to create than lists, which are stored in two blocks of memory to allow for changes.
Tuples are often used to store heterogeneous data (different data types), while lists are used to store homogeneous data (same data type).

1. What is the key difference between a tuple and a list in Python?
2. Explain why tuples are faster than lists when creating a large number of elements.
3. Describe a scenario where using a tuple would be more appropriate than using a list, based on the type of data being stored.
