Getting Started with Python Lists
Explore the fundamentals of Python lists, understanding how to create mutable ordered collections, access elements using indexing, work with nested lists, and merge lists. This lesson helps you write efficient code by mastering essential list operations and applying them to solve problems like merging sorted lists.
As discussed previously, a list in Python is a versatile and ordered collection of items, which can include a mix of data types like integers, floats, strings, and even other lists. Lists are mutable, meaning their contents can be changed after creation. They are defined by enclosing items in square brackets [], separated by commas, as shown below.
