One Pager Cheat Sheet

• We will discuss arrays and learn how to store and manipulate multiple data values in our program.
• Arrays are a data structure that can store a collection of values with indexes and a specific length, making it easier to group similar elements in a program.
• In Python, lists are used to store multiple elements of different data types, such as strings and integers.
• Both examples of list initialization in Python, with different data types stored as elements, are valid, and neither would generate an error.
• Various operations such as adding, removing, searching and printing, can be done on arrays to make their usage in programming more efficient.
• In Python, list operations such as append(), pop(), remove(), and len() can be used to manipulate and access information about lists (or arrays).
• The .append() and .pop() methods of lists are used to add elements and remove the element at index 2 respectively, resulting in the list ["Ford", "BMW"].
• The code provided will output 7, as this is the element located at index 2 in the list numbers of elements 3, 2, 5, 7, 3, 6, due to Python's indexing starting from 0 for the first element.
• We discussed arrays and the variety of operations that can be performed on them, which can help us to create meaningful programs and applications.
