python pls

(a) A design choice we discussed in writing Python programs is to make sure to never write code that isn't in in an if _name__ == '_main_'statement, a class, or a function definition (except for global constants). Why is that the case? Mark an "X" for the answer(s) you choose. _In order to separate the executable module from the rest of the modules in the program To ensure we have a clear "starting" or "entry" point for the program Without doing so, the program would not run at all, per Python convention All code in Python must be within a function or an if _name__ =='_main_'statement To prevent unwanted output or actions from occurring during program execution
