Today’s lab in class we practices what we have read for homework. The topic function. The first we learn about the Syntax of the function, it just like how to def a function and print it. The second practices is too importing Modules. You can import any math symbols you want from it. And the last one is Built-in functions it just let you use all the techniques you knew from previous steps and apply on it. And on the taking a vacation questions some times you need to find where you did wrong , for debugging the process takes time and will make you think a lot sometime will leads you to frustration. But when you solve it you will feel proud of yourself.
