The four steps to defining a function in Python are the following:

1. Use the keyword def to declare the function and follow this up with the function name.
2. Add parameters to the function: they should be within the parentheses of the function.
3. Add statements that the functions should execute.

Why is Python throwing an error when trying to open a variable?

No worries 🙂 welcome to Python! It’s throwing that error because it’s looking for a global variable that doesn’t exist — and the reason it doesn’t exist is because you’re not hitting the if type == “accounts” condition! That will clear the error and at least let you see what other bugs may be popping up 🙂
