| ## Overview | ||
|
|
||
| In any non-trivial calculation, we want to let our computer remember | ||
| things, such as the content of a data file, or the parameters/settings | ||
| we use in our program. Variables allows one to make a computer | ||
| store ('remember') information. Here we use our first simple variables. | ||
|
|
||
| Also we practice converting an equation and a mathematical problem | ||
| to Python code. We will discover the helpful modulo operator. | ||
