We already know that a variable isn't a 'memory cell' that stores a value. Python creates an object, and a name starts referring to it. But that raises a new question: where is the name itself stored?

In the previous article, we learned about the `while` loop. It is great when we do not know in advance how many times an action needs to be repeated. But very often we already know that we want to iterate over some set of data.

In the previous article, we learned how to make programs make decisions. But what should we do when an action needs to be performed many times?

When the last reference disappears, Python knows the object is no longer needed and frees its memory. At first glance, that seems like all we need. But let’s look at a small example.

Until now, our programs always executed in the same way. But often a program needs to make decisions.
