Bob Builds a House

Let’s combine the square and triangle code to create a drawing of a simple house.


The program below has blank lines between the lines of code. The computer ignores the blank lines. We add blank lines to programs to group lines that are working together such as the lines below that draw a square. Often a comment (starts with a #) is used before a several lines of code to explain the purpose of the code.

Let’s imagine going on to make another partial square along the slope, to create a “chimney.”


Let’s make another square inside the house, to create a “window.”
