NameError: name '***' is not defined

What is a NameError in Python? What can you do to fix it? When does it happen?

All these questions are answered in this video!

The NameError in Python means you've tried accessing a name (variable, function, or module) that doesn't exist in the scope that you've accessed it in. For example, "NameError: name 'os' is not defined" could mean you've tried using the 'os' module, but forgot to import it—so it doesn't exist.
