Thanks, Mirielle You’re right: >>> type(None) <class 'NoneType'> >>> type(False) <class 'bool'>

Prof. Dr. Zoltán Vass None and false are very different in type: None is a datatype of the type "None" False is a datatype of the type "bool" Thus when you type: None==False It will return false because these are not the same. But if you change your code and write: bool (None)==False. It will return true. Because none being the datatype none it will return a value of bool equal to zero. Thats why it will return true
