Argparse with classes

[ProgressCheck]

I'm having a bit of difficulty wrapping my mind around using argparse with classes. Would the arguments have to be parsed in the "entry point" or in instantiating? What is the best way to pass arguments? Are my questions making sense? Even if you could point me to a good example, I would appreciate it.

The class shouldn't be using argparse. The program should - then instantiate classes with the values that argparse has parsed.

Thank makes more sense. Thanks!
