Can we say that Primitive data types are like the basics things that all human beings can do, but in this case it will be the functions that are inbuilt within the computer?

I suppose that’s one way interpreting it.:thinking:

On my evaluate function, what’s the meaning of the Outoput equals to 1?

As I understand it, the output is the expected answer of the function - in this case, it is a Boolean value where 1 = True and 0 = False.

Out of curiosity, why doesn’t the Capitalise function turn True into TRUE? How does it know the difference between a Boolean value and a string/word?

I would like to know the answer to your question as well.

I think “True” is a predefined word in programming.

Welcome to the forums!

You’re correct in that True can have a different meaning in programming. In this exercise, True is a boolean. However, be careful, as "True", with the quotation marks, is a string, not a boolean.

Booleans in programming are either true or false. They are written differently in different languages (True and False in Python, true and false in many C-family languages, etc.) Other data types can also be evaluated as booleans (1 is true and 0 is false, a non-empty string is true, an empty string is false, etc.)
