The concept of lettering.

write one or several small programs to develop the concept of lettering. Lettering is a technique for using letters to generate images/drawings/paintings. You will also use functions. Functions are used to organize chunks of code to make the programs easier to read and to use. Custom functions are described as “user-defined” because we write them and name them. Built-in functions are part of the programming language and we use them as they are given to us.
