Variables, Functions, and Lists

Learn to work with Python variables, functions, and lists.

We'll cover the following


Variables are names given to a value so that when the same name is used in the program, it invokes the associated value. Simply put, when we tell a program that we have a variable called Dollar, and we assign a value of 50 to it, then whenever we use or refer to Dollar, we get the aforementioned value.

Variables point to the information or data stored in the memory location with a value, such as integers, lists, real numbers, strings, floating-point numbers, booleans, and many more. Variables can also have custom data types assigned to them.

By the way, we’ve already seen and interacted with variables back in the string manipulation script.
