title: 'class' object has no attribute 'method'
body: <p>I'm getting an error "AttributeError: 'Test Employee' object has no attribute 'increment_salary'". Not sure why I'm getting this error because 'increment_salary' is a method, not an attribute and I'm 99% sure I created it correctly. I've searched and the only answers I saw said to check mix of indentation and spaces so I went through and triple checked every indent. It may be wrong here because I am not familiar with how to copy code here but I am sure I did it right in geany.</p>
