Read args only when needed to allow importing the module

The arguments should not be read on top-level code, only when the program is executed.

This way other Python code can use the module functions.

Thanks @Depaulicious. In future, please make sure that you create an issue before creating a PR. Have you test it for all the functionalities?

Yes
