--description--

The expenses parameter of your add_expense function will be a list of expenses. You want to be able to add items at the end of your list. For that you'll use the .append() list method.

Add a call to the .append() method on the expenses list. Don't pass any arguments to .append() for now.

--hints--

You should have expenses.append() in your function.

({ test: () => assert(runPython(`_Node(_code).find_function("add_expense").has_stmt("expenses.append()")`)) })

You should not have pass in your function.

({ test: () => assert.isFalse(runPython(`_Node(_code).find_function("add_expense").has_pass()`)) })
