So far, it's a simple class, but I can't understand why I get a NameError for a function that exists in the class. The function is declared on line 15, 'getby', then called on line 25. My code editor (VS Code) underlines it wherever it is called, hinting that it isn't defined, as if it doesn't exist. I have changed the name with the same defect. Any reason this is happening? Thanks

NameError: name 'getby' is not defined

There is no function named getby. class Browser has a method named getby. You can call this method using Browser.getby(browser_instance, locator_type), or use the more common syntax browser_instance.getby(locator_type). In your particular case you have a handy browser instance named "self" (use self.getby(find_by)).

I knew it would be a simple oversight like that. Thank you
