Python Data Structures
Creating a List
Data structures are essential tools for organizing data, allowing for more efficient access depending on the specific needs of a program. They form the foundation of any programming language and are central to building functional and effective programs. In Python, the main data structures include lists, tuples, dictionaries, and sets, each offering unique features and capabilities. In this course, you'll learn about these structures and how to use them efficiently in your projects.
Understanding Python Lists
Python lists are ordered collections that are mutable and may contain elements of any data type. In Python, a list is created by putting the items inside square brackets. Here's an example:
# City name, population, area, is a major metropolitan city_info = ["New York", 8419600, 468.9, True] print(city_info)
As shown, a list can contain a mix of different items or even be completely empty. Take a look at the following example:
To initialize an empty list, simply assign empty square brackets to a variable.

Your goal is to create a list named travel_wishlist containing at least two cities you dream of visiting. Each city should be represented as a string. Be creative and think about places you’d love to explore!
