    python # string variable STRING = "# This is not a comment." Python Numbers. This option offers you a variety of possibilities.When the module contains only classes, functions, variables, and constants definitions, you probably won’t be aware that the code was actually run, but when the module includes calls to functions, methods, or other statements that generate visible results, then you’ll witness its execution.This provides you with another option to run Python scripts:You’ll have to note that this option works only once per session.
    One of the most important skills you need to build as a Python developer is to be able to run Python scripts and code.
