Which of the following statements is false? To view a list of identifiers defined in a module, type the module's name and a dot $(.),$ then press Tab. To help distinguish "constants" from other variables, the Python style guide recommends naming your custom constants with a leading underscore L$)$ and a trailing underscore. Python does not have constants, so even though pi and e are real$-$world constants, you must not assign new values to them, because that would change their values. In the math module, pi and e represent the mathematical constants a and e$,$ respectively.
