Naming Everything¶

Learning Objectives:

• Learn how to define new functions and procedures.
• Learn that we can use libraries containing functions and procedures written by others.
• Learn that any name can be renamed, even Python’s internal names.

Earlier we learned about how a variable can store a value in a memory location (box). The “value” can be anything. It doesn’t have to just be a number or a string. It can be steps, instructions, and even other names. This ability to name other things is key to Alan Turing’s vision of a computer.
