I have the following code:NetBeans gave me a suggestion to change it to this:I looked it up and found that __null is called a "compiler keyword", which I assumed to mean it's used internally for the compiler. I don't understand why NetBeans suggested to change it to a compiler keyword.
This question already has an answer here:As per my knowledge, final variables must/can be initialized only once otherwise compiler is supposed to throw an error.
I am currently using Python3 in Jupyter Notebook and I just ran into a keyword exit. What does this keyword do ?
